I ran these through Genetic Genie and Promethease (too much info on that one). Any immediate things to note?

You have two First Priority mutations - CBS and SHMT. The CBS is the minor one. Just about nobody needs to treat for CBS if they have that one. However, you also have several BHMTs, which can also add to CBS, so it's a "maybe" if CBS treatment would be needed. However, you seem to be tolerating methyl supplements well, so CBS is probably not a problem.
The next one is SHMT. For SHMT you take folinic acid. This helps the folate cycle make DNA and RNA bases. SHMT is also one of the "leaky gut genes". You may need to treat SHMT while treating the gut to be successful with gut treatment. You report gut problems and Rich's SMP having NO effect. This could be due to the gut not absorbing nutrients.
Now that you've improved your gut, things should be better this time around.
Then you have MTHFR C677T and A1298C, so some methylfolate for that.
You have several MTRRs (B12 recycling), so some B12 for that. With your COMT/VDR combination, you have the most sensitive combination. Yasko suggests mostly hydroxcobalamin. You report doing ok with methylcobalamin shots. Based on your SNPs, you should be jumping off the ceiling with mood swings! I'm not exactly sure what's going on there - it's hard to tell the timing of things, amounts and so forth from your description.
For BHMT, take lecithin to produce TMG and get the secondary methylation pathway going.
For VDR Bsm, you're already supplementing vit. D, so you're good there.
For MAO A, Yasko suggests sprinkles of 5htp, only after the rest of the pathway is supported and if you're still having mental health type problems. This is contraindicated if you're on an SSRI/SNRI.
Killing bad gut bugs and getting methylation going will detox metals in and of themselves. There's no need, and it could actually be too much to add other metal detoxifiers on top of this.
You should have some nicotinic acid on hand in case your COMT mutation starts acting up. See the Start Low and Go Slow document in my signature.
Also one other thought - if you're not getting a response once again. You could be one of those people who require very high amounts of methylfolate - like grams instead of mg. I'm not sure what this is due to - either gut issues or FOLR mutations is my guess right now.
One other idea is a MAT mutation, which would block production of SAMe. So some direct SAMe supplementation would be indicated in that situation.
