A couple of additions
You might think of adding the road to McCarthy and the one to Manley Hot Springs. Otherwise you have it covered pretty dang well. Alcan Rider is the man to listen to. I assume you have discovered the "Alaska Primer" thread in this forum. If not, then check it out.
Surprisingly, we have little attractive true off-road routes up here, but the numbered routes are often so bad its like being off road. Most of the trails are beaten so hard by the 4-wheelers that they consist of muddy trails with big round rocks hidden in the puddles.
If you drive the routes you have named, you will eat up a good part of the summer. Take youir time and enjoy.
