Well I'm out for a food break but here is some of the progress, as well as some things I learned and tried. Started my day with the knolling of my pieces

Also, one of my favorite things about foam is being able to fake it till you make it. It's very forgiving, and you try hard enough, you can make it line up.

Also another thing I tied out which worked well, was scoring the foam on two bits that we're flush with each other. The hot glue likes to fill the gaps between, so in a flush piece, it will hold it together better than the two smooth surfaces.

And finally, it also works to fill and shape gaps sometimes. It's hard to see in the picture, but the glue is smooth all the way around, filling the Gap and fixing the rough cut. Also with the rough side of the foam up, it lets me hide a few crimes. The transition doesn't have to be completely smooth.
