Well, for starters, you definitely don't need a third vessel to age in. You can secondary in a carboy or better bottle if you like, or just give it a solid month in primary, verify you're at FG, and bottle or keg it for aging. As for aging out the 'alcohol burn', that screams out that you're fermenting too warm. Do you have temp control ? What temp do you pitch your yeast and ferment at ?
EDIT - Also, I'd drop the almonds at very least - they contain oils that could hurt head retention and honestly serve no purpose here. And multiple grain bags would be ok, but better would be to steep the grain loose in 1/2 gallon of 155F water for 30 minutes and strain them through a sieve or colander.
