Also, the Open Yale Organic Chemistry lectures with J. Michael McBride explain quantum physics in a straightforward and practical way without all the usual mysticism and "this is not possible to understand".
If you are going to do a PhD you should have a research project decided on before you start and you should have your own funding from a grant that you wrote yourself. If you are not ready to write a successful grant application you should take some time to read and talk with people in your prospective field, while having some other job.
