I don't see a reason to ban plastic surgery. It's a new feature available at the hospital for a price. Sometimes the surgery goes well and the player can choose new features, and sometimes it goes badly and your Sim ends up with crazy features. I believe a reversal is available, also for a price.
Sorry if this has already been answered--I don't have time to go through 150 pages of questions. By Travel opportunities, do you mean Adventures, or the ones you get at home that say, "Go to X location and do something (usually involving fruit)"? Please let me know; I have just installed Pets and would like to start my Dynasty soon.
Where is says in the rules that "travel opportunities" cannot be used as a BlackOps, it's referring to the adventures you get while in one of the three vacation locations (Shang Simla, Champs Les Sims, and Al Simhara). Any opportunity that you get while in your home town that fills a slot on your opportunities tab is good for BlackOps.
Metro: It might be a good idea to change "opportunities" to "adventures" in that part of the rules to avoid confusion. I don't think we were using the right terminology when writing the rules, now that I think about it.
