Your learning sabbatical seems very well thought out and I'm glad your documenting your journey publicly so others can learn with you.

I actually started down a similar path to self-learn AI, but ended up going the conventional Masters degree route. I even setup a skeleton of a blog to document the journey.

The home page has some courses you may want to add to your resource list. I've taken quite a few courses on Udacity and have enjoyed almost all of them.
