MoveObjects on - I have to be careful with it, as at times it can interfere with pathing when I place something creatively, so for things like placing chairs at chess boards and dining tables, where I need to know the furniture will work there, I turn it off.
I am also pretty quick on the Motherlode cheat. Also, TestingCheatsEnabled true, for mailbox options, editing sims on the fly and the motive and relationship sliders. Not all the time, but if I have to have all my Sims free to do something (a wedding, a bitrthday party) I'll top them all off so they don't wander off to do something else when I need them to be someplace specific.
