Need a review of my airbag set

[VA72C10]

I have decided to bag my 70C10 Longbed fleetside 1/2 ton 2wd with a 350/350 combo. I just want some confirmation on my decisions and anything i might be missing or ordering wrong noticed before i order everything. Or worse, missing something when i'm tearing it down and having to wait for parts as i will only have help on certain times to work on it.
First off, i just want to be able to tuck the tires at local shows. I am not looking to lay frame and do not want to mess with the inner fenders or the bed. I just want a reliable system with control to raise lower at least the front and back together if not all four wheels individually and definitely an all dump/all raise option. Not concerned with the speed as long as it's not a few minute fill time.

The current setup i've decided on:

4 Slam Specialties RE7 Bags
2 1/2" drop spindles in the front
New shocks
CPP Shock relocator kit in rear
1/2" or 3/8" air lines....not sure yet
7 switch EAI air ride controller
Suicide doors.com front plates/cups
Rear bags to be bolted in stock location
5 gallon air tank
Viar 380 dual compressors
3/8" valves (6 or 8 haven't decided)
Brass fittings
145/150lb pressure switch
No C-notch planned.....yet, but i'm considering it.....best option?
2" blocks in rear if that will help???

Any glaring weakness on the system...anything i am overlooking? Do i need to run sway bars with this setup? I am not planning on this being a daily driver. Just weekend cruising and picking up stuff from the hardware store every once in a while.

Will i be as low as this beautiful truck below without a C-notch?




Should i install 2" blocks to get this low in the rear or will i hit something before that?

Do i remove or shave the factory bumpstops as the RE7's have internal bumpstops?

Side note: I'd like to plumb an additional fitting/hose to be able to fill up a flat for me/friend...is that as simple as making sure the air tank has an extra fitting and installing a valve or is there something else i need to do?

Thanks for any/all comments and suggestions....I'm only doing this once and want to do it right and on as much of a budget as possible.
