Well I ....

Finally cleared H Gundrak!

castrandom elemental shaman macro helped...
Healing only during rhino phase with priest/shaman helped...
Using Divine Protection (after not even knowing the spell was in my spellbook until getting a tip on these boards ) helped...
Tailoring new pants for my healer/2 DPS helped...

But most of all...

dual-boxing.com helped.

Thanks all. Again and again I say, great community here.

FYI. Funniest part of this whole thing? I had one wipe and... it was on a three snake pull. Didn't die to any of the bosses.
