Following the Avia or Sound and Vision type setup discs are great, very easy.
Stick to that and most of your home calibration for audio and video should be taken care of, short of having a pro do your projection unit as mdrew mentioned.
THAT may be worth having a pro do the work.
I've delved into the service menu with our now 5 year old Toshiba CRTV and it is not that touchy, but finding the proper info is tough.
