What I don't understand is why you need to build another floor on top of the crushed stone floor you already built? Why not just use PT sills and frame the walls right on top of the foundation, as if it were a concrete slab?
I do gusset both sides but single side the outside truss. If you are not going with a ridge beam you should go 16"oc. With a ridge beam you can do 24"oc.
If you put a 4' door in, guaranteed you will need to get something 4'3" through the door in a month or so.
Just a couple of observations. You should double or triple the outside corner where the other wall butts up. If you're going to put sheathing on the inside, make sure you leave yourself a nailing edge.
Also, after you finish your front wall, be sure to add a second 2x around the perimeter, bridging the other 2x top plate. It'll make it solid.
For the door, a 5' door covers most bases. You can get an overhead garage door or a roller door like the mini storage -- that's what i use. If you go with a roller door, I recommend you put in a man door if you plan to go in and out allot.
Looks great so far.
I'm thinking about this for exterior paneling:

For $25 a sheet, that's pretty cost effective
Any other products I should look at?
Good product that is ready for paint.
