To ride at that height, you will need to cut about an inch off the lower cups. I would recommend the CPP bolt in notch or something like it for the back, then weld it in for security. You could use a pipe, but it requires a bit more work and the notches are only $100.
I got the drop shocks for my truck and found out the front was too short. It limited the lift I got with the RE7 bags by nearly 2". I kept the rear, but they also limit the lift I get by at least 1.5". That is with shock relocators as well.
For air management, I just have 2 dual needle gauges ($5 each off ebay) and a 7 switch box ($35 off ebay). I am running 8 1/2" valves, but would recommend using 3/8" because the fill and dump was too fast to control. I bought adjusters to decrease the speed. It would have saved me about $200 if I would have just used all 3/8" tubing and valves.
Hope that helps.
Here is my truck at full dump. I have a 3" cup in the rear (no notch) and I have not cut my front cups. I am using a 235/75-15 tire.
<edit> you won't be driving at full dump, so you will want to be about 2" or more lower overall.
