My brakes and suspension are garbage!!

[Daniel 61 Apache]

Hello. Before I go spending a butt load of money I thought I'd have you guys critique my choices since I'm new to these trucks. Here's where I'm at with the truck right now.

Right now my truck is falling apart.
When I bought my truck the rear shocks were converted to a coilover shock and the coil spring was scrapped to achieve a low stance. But, the coilover shock was a little too short. So they drilled a hole in the frame, welded a bolt to the frame rail, and attached the coilover. Crappy craftsmanship, results in crappy performance. Now the driverside rear coilover has ripped out of the framerail and the trucks leans like a rapper trying to look cool..... Sometime ago, someone also cut and ripped out the rear brakeline. No rear brakes at all. The front brakes feel like they're a couple of pencil erasers rubbing on the drums so I'd like to fix that as well. I don't want to be ghetto so I'm going to try to do this the way it should have been done the first time.....Right.

Here's what I plan to do with it.
I'd planned on going with a front disc conversion kit and rear drum rebuild kit from www.earlyclassic.com. The front kit, here, is $995 and comes with "Master Cylinder, Proportioning Valve, Brake Lines, Brake Hoses, Calipers, Pads, Rotors, Bearings, Seals, Dust Shields, Dust Caps, Castle Nuts, Slotted Washers, Banjo Bolts, and All necessary Hardware and Brackets" according to their website. I'll also be getting a rear drum rebuild kit from them also. Next I was going to buy an airbag kit from www.*****************. I was going to use the "build your own custom kit" option. The parts I chose were the following:

KP 200 PSI Single Needle
9 Port 5 Gallon Slim and Skinny
Slam Specialties 7" RE 200 PSI Single Port (Front and Rear Bags)
SMC 3/8" Fill Valve
Viair 380 150 PSI Compressor
50ft of 1/4" DOT Reinforced Air Line
KP 200 PSI Dual Needle
AVS ARC-T7 Trans Polished 7 Toggle Switch
Viair Pressure Switch 110/145 PSI
SMC 3/8" Dump Valve
50ft of 3/8" DOT Reinforced Air Line

Is there anything that I might be missing or anyone have any advice? My truck is a 61 and I can't find any kind of bolt in air ride system. And early classic is the only place that I found offering a "bolt in" setup for discs. I'm looking to purchase this all in the next few weeks so any help would be greatly appreciated.

Thanks, Daniel
