Air ride suspension

[wwotr]

I'm new to this technology and need a few basic questions answered.
I've got a 72 GMC Short Fleet that has been lowered with CPP Spring/Shocks.
It is 5.5" in Front and 6" in the Rear.
Now that I've moved into the Palm Springs area, there are a TON of,
"Dips and Speed Bumps". Also the posted speed limits on (most) of the City Streets here is 50 Mph
My ride is unforgiving and bottoms out on the roads down here.
I'm wondering if an Air Ride System would give me a smoother, more responsive and
Forgiving Ride, (than my current set-up).

So my questions are:
1) Is it adjustable from inside the Cab?
Does it look like those Low Riders Cars that have a BIG BOX sitting on the Front Seat,
or is it a nicley tucked away switch?

2) Can you adjust the Front/Rear seperatly?

3) How do they install?

4) Does it go inside the Spring, do you still use shocks?

5)Where does the Compressor go?

6) Last but not lease, what are the prices for a nice dependable,
"Entry Level Kit"?

7) Who/How much is it to install them?

Any pictures of your Air Ride "set-up" along with some pictures of your Trucks stance would be appreciated also.
