and im going to get a 7" wide screen of some sort but i also want to keep the head unit i have, what else am i going to need to make this work?

umm.....make sure your head unit has aux. out puts. you wont need a tv amplifier unless you have 3 or more tvs.........so really it sounds like you got it covered i guess.
