Check to see if a 94 valve will fit, then use it.It is better calibrated for 134a . It will cool a little better, and more importantly keep the head pressure (high pressure side in the compressor) down so the compressor doesnt work so hard, and lives longer.
If you have O rings to replace the areas that you are dissasembling , use them. If not, as long as they are pliable, and are not deformed to the shape they are when installed under pressure, use them.When an o ring takes a set to a shape other than round, either circumferentially, or radialy they are NOT OK. Naturaly any O ring that is cut or split is a no brainer. Hope this helps.
Do I have to remove all the old oil (mineral) from system/AC compressor or would PAG be fine in it?

Ideally you would flush it out and get it clean. Synthetic PAG mixes with ALL oils , that takes all the worry out. get system clean as possible, and assemble. It will be good to go.

compressor problem.. Like a weak cylinder, or a faulty reed plate.

I remember that system wasn't vacuumed before charging it with R134a. would this cause moisture problems, etc. I know A/C is not blowing real cold. Should I evacuate, vacuum and recharge system?

ac = problems

all posts are great info !! do it all! I would suggest - as likely the evaporator was =coroded inside- to flush the entire system out with a flushing agent too! prior to replaving any driers.Likely also will need a new compressor. dont be cheap as if system is coroded?? that stuff is already in the compressor!!
