I did search the forum and didn't see a fully devoted topic, nor is this sort of topic on the website. So here is my bit of info, that hopefully people will add to it. I don't have cheats enabled so unlocking outfits and hair and new furniture really is my excitement in game. Used

Watcher Achievement levels and rewards (complete list) (No photos of the rewards, but still spoiler alert):
http://forum.ea.com/eaforum/posts/list/6973613.page General Tips for Watcher Achievements:
Kingdom planning: For achievements that require all of a type of hero (misanthropes, gluttons/guzzlers, whale ate my parents, all Jacobans, all Peterans) start a kingdom and stick to it. With the misanthropes and glutton/guzzlers, make sure you don't get legendary traits until you get your desired achievement. I kept a note next to my monitor reminding me. If you accidentally do get a legendary trait or forget and make a hero with a different flaw, time to have them meet the watcher (dueling or pit monster) and hopefully you didn't have an heir.
Ambitions coinciding with Kingdom Achievements: Some ambitions sort of throw you into a achievement if you sort of guide your kingdom levels that way. For example, with the Thoughts & Prayers ambition, try to aim for 'Watcher's Protection', 'Brains over Brawn', 'Dead Sim Walking', and 'Frustrated Doc'. Similarly with Safe & Sound, 'Watcher Who?' and 'Forbidden Magic'.
So achievement specific tips, some achievements are self-explanatory:
Well-versed : Perform poems 50 times - easy one. Just make sure your bard has a poem in inventory and this completes itself on its own.
A Bard's Day Night: Quest with Bard 30 times
Beowulph: Write Beowulf - Epic poem named Beowulph with inspirations Food/Drink, War, Kingdom/Loyalty in that order
Prolific Playwright: Write 20 plays in one kingdom - sit down and write 20 plays, go with comedic as they take less inspirations, name them whatever (I numbered them).
To Be or Not to Be: Write legendary play - Supposedly, Legendary Play named 'to be or not to be' (with out quotes) with inspirations Kingdom/Royalty, Love, Art, Sickness/Death, Foreign Lands in that order.
Dressed for Success: Craft 50 pieces of armor - If you are looking to hammer out this ambition (har har) in a row get *a lot* of crudium and ferrous. Keep making crude plate mail or ramshackle armor.
If I Had a Hammer: Quest with Blacksmith 30 times
Darkness Unleashed: Craft legendary Doom Sword -
http://www.carls-sims-3-guide.com/forum/index.php?topic=5596.0 To ensure legendary quality use the angelshammer, and be careful when making.
From Here... : Place 25 total buildings
...to Eternity: Place 100 total buildings
Clever Swordplay: Win 200 swordfights total - I believe this is duel fights not sparring?
Sovereign Study: Train the Spy and Knight with the Monarch - Both have dummies in their respective quarters, so head on over. Or, turn the marker on, and if in a buildable lot, place a dummy.
Carry a Little Stick: Win a swordfight with worst sword - Crude longsword, hedge your chances and have full moodlet, and if possible luck potion, potion of preparedness. I picked to fight the town crier since, they don't practice on the dummies. I'm sure this is duel only
Deposed: Defeat the Monarch in swordfight - I'm pretty sure this is also from duel. Good with a double person quest with your spy/knight with the monarch. Have your monarch equipped with terrible stuff and low rested, bad mood, etc.
Let There Be Rock: Discover all minable minerals - Pretty easy, just find them, look behind buildings and in little nooks with your wizard or blacksmith.
Herbal Hexplorer: Discover all harvestable plants - Easy, with your physician or wizard.
Botanical Boon: Gather herbs 50 times - Very easy, can even accomplish with wildflowers
Passion for Poison: Have 25 nightshade in inventory at once - Designate a sim to hold it all, wizard is great for the growth spell. If you have another sim who has nightshade in inventory share!
The Chosen: Have every hero sim chosen by the Watcher - With 12 Culture, ability to be chosen unlocks, self-action. Takes a bit of planning (used a notepad to checkmark each hero), great with Thoughts & Prayers.
Watcher Protection: Reach 10 Culture with just 3 Security - Great with the Thoughts & Prayers ambition.
Dead Sim Walking: Build 10+ buildings with Well-being at 3 or less - Great with Thoughts & Prayers ambition
Graveyard shift: Have 30 sims pass away in one kingdom - Be sure not to overwork the constable with the pit monster, remember you can also duel to death, thus faster.
Poker Face: Win 100 card games
King of Kingball: Win 200 Kingball games - Have 2 heroes play each other, one with best paddle, one with worst. Each win counts towards this achievement, also has a chance for having the Underdog win (Thanks Kaliope)
Moral Ambiguity: Cheat at cards with Peteran Priest - the ability to cheat is on table during the actual game
Underdog: Win a Kingball game with worst paddle against the best - Keep your rookie paddle! I would think practicing Kingball a lot then pick a low level hero with whom you've equipped Excalipaddle, drink some fortune potion and be in a good mood. Further hedge your chances if you have wizard active in quest and curse, the opponent.
Gluttons and Guzzlers: 5 Drunks and 5 Gluttons in one Kingdom - Takes a bit of planning, be sure to have no legendary traits. Low traffic places are great for drunkards (wizard, spy) and replace fireplace crock with oven and buy tons of wheat. Oven recipes don't spoil as soon, yet the buffs are shorter.
Plastered Perpetuity: Be drunk for 24 hours
Gruel Hoarder: Have 25 bowls of food in inventory at once - Great with the Meat Quest with your merchant. Chef from Gatrobury comes and constantly cooks gruel. Move to inv.

I'm on a Boat: Trade via boat with Merchant 100 times - I've read that it must be items traded not simoles, but handy just to trade single items at a time. Also handy to put multiple items in boat for different ports, then queue up. Such as having 6 barley and 2 mushrooms in boat, then queue two trades, one to Tredony, next to Crafthole. It saves the little snatch of time from opening the cargo hold.
