1.) i'm 95% sure it does(most tv's have them), but it is through the service menu which i dont know how to get into. a simple google search can probably get to it.

2.) leave the contrast and/or brightness pretty low (just to the point where you're getting a good picture...but its not super bright) for the first +-100 hours and you'll be all set. most likely, you wont even have a problem with it.

ps: burnins on most plasmas are VERY fixable.
