questions about install of deck and speakers...

i just got my 1993 g20 (not a t) a couple of days ago, and now want to install my kenwood deck myself. im going to pick up the harness tomorrow. I've never taken out a factory deck before and was hoping that someone could shed some light as to any special tools needed to pull it out and whatnot. Also if you have any tips for me. I hear a lot of people talking about a bose system, is that factory w/both standard and the touring? or just touring? what is the factory wattage for the standard deck? And how easy is it to take off the door panels? hope you can help me out, thanks.
