Help, air suspension, sunroof and NAV???

[H2Singh]

Hi to all, I'm new... 3 questions before I make my purchase.
About to purchase new '05 H2 SUV - Lux

Q.1. Do I need air suspension for load leveling if I plan to carry 1000 pounds in the back with 2nd row seats down once a week. Or is the regular suspension sufficient. I do not plan to off-road, beside dealer sponsored events.

Q.2.Any complaints from friends who ride in back seat of an H2 with sunroof because of the lack of headspace and if so, is there a way to permanently make the back seat slightly reclined a few degrees. I am 6 feet and when sitting upright in the back, my head was touching the ceiling. I am seriously thinking of not getting the sunroof b/c of this problem. (all comments welcome).

Last questions, hate the fact that can't play CD with the NAV system on, so can I get an aftermarket system that meets my needs and still use steering wheel controls for volume, etc.. or is there a way to get a separate cd changer attatched to system - which is better??

thanks for your advice and comments - sorry for any sp mistakes.
