Would all the joists sit on top of the outside walls? That does seem easier and after I think about it, much stronger than hanging from the side of the wall.
I tried making the wall level and plumb but you know how it goes.

I was kinda surprised myself at the price of lumber. Right now it's 1/2 of what it was two years ago. A board foot is 1"x12"x12", so a 22" 2"x12" is 44 board feet. Lumber is now $229/1,000 b.f. so you can check my math.
Setting the joists on top of the walls is the easiest way to go, in some respects. You need to block every joist to keep them square and if you can't frame a wall square & plumb you might have some difficulty installing the joists this way. Actually, it's pretty simple. Just toe nail up a rim joist and nail your joists in between. If you lay out your spacing on the rim joists on the ground - mark the edge of the joist with a square & put an X on the side the joist goes on - and just get your boards straight one at a time, you'll do fine. If the length of your room is greater than the length of your lumber, be sure to stagger your splices on each wall.
I guess it can be easy to build your walls a little cattywhampus, I just don't remember how to do it that way. If you start with a level surface, most of your vertical members will be the same size, so count what you need and cut all that lumber at the same time, to the same size. If cutting is your problem, invest a couple hundred bucks in a miter saw. You can set-up a jig and cut studs real quick with a miter saw. If you want to make real square cuts with a circular saw, use a framing square (one of the triangular ones) as a guide for your saw. Measure twice, cut once. Remember your saw blade cuts about 1/8", so you need to measure for each cut. (IOW - you can't take an 8' board, make a mark every 2', cut those marks and end up with the same size boards.) Lay out matching top & bottom plates before you start nailing. If you aren't sure about something, get some 10d duplex nails and temp it together then make any adjustment needed. Use the green 16d framing nails, they go in easier. If your wood wants to split, tap the point of the nail with your hammer a couple times, blunt nails split less than pointed ones. Of course, if you want to get really good at carpentry you need to learn how to use "fuck", or derivations thereof, as a noun, verb and adjective in the same sentence.
Good luck with your project. I hope some one that helps!
