Elevated - Theres' tons of options out there head unit wise. I like the Kenwood 700U as it opens up and you can store you iPhone / pod in the unit and charge it. And it also gives you integrated playlist control on the transom remote. for 200-250 you cannot really go wrong here. I know of 6-7 boats off the top of my head that run that deck and its great. I think Mandley has one. talk with him and get his user take.

This deck also provides 3 sets of rya outputs (and good output voltage) to individually feed your amplifiers. As for the fader control of the tower zone you might look at a simple PacLC1 controller, or the kicker piece, or step up to a eq that does all the zone control functionality built in. Clarion makes a good one and so does wetsnds.
