Air Ride Shopping List

[Pastdue72]

I am looking for VERY detailed shopping list down to if you need brackts of some kind to keep the line in place along the frame. Would also be nice to have a little clarification for the differences in Compressors.
For example the two compressors I am looking at are as follows:
http://www.*****************/air-mana...ir-380-200-psi
and
http://www.*****************/air-mana...150-psi-silver

Now back to list at least as I know it:
Air Bags
Brackets to mount bags
Fittings for bags (need further clarification on what all the entails)
Air Line
Compressor
Air Tank (what is the minimum number of ports you could use)
Air Valves (or in my case I am looking at a AirValve Manifold example in link http://www.*****************/air-mana...150-psi-silver )
Gauges (please clarify on how many) I would like to control all 4 bags independant
Switches to control the bags
Pressure Switch (How many are needed)
Relay???

Please provide as much additional info as needed. I just got my bags in today from Airbagit.com which they are running a sale where you buy 2 get 2 free. My experience has been very positive with speed to ship and polite customer service. We shall see how good the bags are along the way. Seems to be a good deal not really sure about the quality of the product I did read a post stating negative reports to the BBB so buy at your own risk.
