Yasko has a better chart than Heartfixer for this on her new "simplified protocol" page.
http://www.scribd.com/doc/132017201/Dr-Amy-s-Simplified-Road-Map-to-Health It's about halfway down the page. For your combo of COMT +/+ and VDR Taq +/+, she suggests hydroxycobalamin and adenosylcobalamin. It's somewhere in the middle between the two extremes.
In theory, you should start with SHMT, which is taking folinic. What was your experience with that?
CBS would be next, but A360A is a minor one. It doesn't seem to be an issue for the 2 or 3 people I know who have that one.
C677T is a big one, and you'll likely need methylfolate. Your MTR (processes B12 ) is ok, which is good. You have a couple of MTRRs which is B12 recycling. So some additional B12 is probably in order, but you may not need huge amounts like some others do.
BHMT is the secondary pathway, so some TMG for that.
With a VDR taq +/+, for sure get your vitamin D levels tested, and supplement with that if needed.
Something like Rich's Simplified Protocol might be the ticket for you.
