Also, buy a vacuum pump if you are going to do the work yourself. The Seiko compressor is supposedly better than the ND one. I have the ND one because it was all that I could find at the time and I had been waiting on a hand built rotary compressor for months and finally said screw it.

In terms of current state of my system, I am running R12 and orig non-barrier hoses. I developed a leak in the orig evaporator as evidenced by traces of oil in the drain puddle last summer. My static pressure was 50 this AM before having the refridgerant recovered. I think this would be considered low as normal static pressure should be closer to 80-90. Additionally, on Monday it was 70 degrees ambient here and I was getting 70 degree vent temps
I'll be ripping the entire system out tomorrow (except for the rear condenser that I will flush) and installing the components listed above plus a high/low pressure switch.
I plan on having the system professionally charged, but I might see if the local Autozone has a vacuum pump for rent so I can check for leaks and get a good overnight pull to dry it out. My sense is the shops generally don't pull a vacuum as long or as many times as they should to get all the moisture out of the system.
