For upper control arms, either Heidts ("D") or RCC
(dwayne9.addr.com) will work fine. Lowers, I used, and would go with RCC. They use a shock extender to mate with the CR upper shock mount, and mount the lower portion of the shock below the lower control arm center. This gives you a longer shock travel (as opposed to OEM MII) and a nifty place to lift your front wheel with a jack.

Strut rod? Keep it, and use urethane bushings if this is a retrofit. Actually, the strut rods make for a very strong and solid front suspension if you use urethane to eliminate front to rear motion of the lower control arm.

If you haven't put the body on the frame yet, seriously investigate the strutless setups. It must be welded in.

Coating. Rust Oleum rattle can appliance epoxy black will give you just as tough of a finish as powder coating for $6.95 a can.
