Talk to GB / Jeff at PCS.
He has a sub-forum.
Jeff has built of number of 34s and is probably the best combination of price/quality/experience you will find for this project.
Personally, from the parts you listed, I would buy a complete RCM BCG, Grip+Trigger pack (complete) and a flat kit from RTG and send those to Jeff to build.
I may be missing some small parts, but Jeff will help you with whatever you need.
