One way I have been studying up (taking the test in 1 week) is the QRZ website's practice exam. The question pool that they are from officially expired July 1st, but I doubt that is of great importance. If there were any problems I had answering any of the questions, off to Google I went, looking up tons of information for free! To find the tests, Google "QRZ practice test".
As for radios, I will definately leave that to the professional amateurs! I have years of experience with public safety radios, and will probably use that platform until I find myself a nice dual band rig, like the Yaesu 8800r or 8900r.
