One thing you could try would be to set aside a day of each week to focus on learning as much as you can about one of the topics each day. Then set aside any other free-time to create a couple simple project ideas and then by the 3rd week start creating the projects / apps / demos. If you think you could do one of them better by going a different direction then take the time to start-over.

There are plenty of guides and tutorials for each of the subjects you listed, just start with searching each and making a master document of everything you learn that you can review. Use bulleted lists, they're helpful.

Good luck!

Some stuff, like OO and TDD cant really be learned in few days. What you can do is follow some gives about this, read books, go to class and program stuff, its something that you gain knowledge with projects under your belt and with some guidance.
