Am I ready to install window framing in load bearing wall?
Yes, but I'd add a few things...
Firstly, I've done what you're doing many times. It will work just fine. A framed structure is a system, and there's a lot more supporting those joists than you might think. Mentally step through everything that they're connected to and you'll realize that you can almost take the studs out without doing anything else, even without your inner wall.
Now, FreeMan makes a good point about the studs on the inner wall not aligning with the joists, but not quite like he thinks. Joists needn't align with studs below if there's a doubled top plate. That's where your inner wall is lacking.
Fortunately, a solution is simple. Slap three temporary studs against the inner wall, flat, directly under the joists that will be unsupported by the outer wall. They'll run from the concrete to the underside of the joist. Nail them to the inner wall at the top, middle, and bottom and carry on. Everything else is well supported by the foundation wall. The temporary studs rest on the slab, which in turn rests on the footing below (or very close to it). All good.
