1. Yes, code written for 2006 will work on a 2007 controller.

2. No, 2007 code won't work with a newer compiler. Or, atleast, results are not guaranteed.

3. Any drive should work, as long as your file names are under 64 characters.

4. See above. The 2007 RC was largely identical to the 2006 RC from a programming standpoint. There were some changes to the master code and a few other glitches per usual, but the overal code structure and programming process hasn't changed much since the big switch from 2003 to 2004. 2004 to 2005 was a small change, and everything's been the same since then, basically.
