Visual Studio can nicely be uninstalled, but you need to use the main setup for this. Do NOT try to uninstall it's dependencies on your own. It will take care to remove the installed dependencies fine.
I had VS 2003, VS 2008 and VS 2010 installed (in that order). Then I uninstalled VS 2003 without problems, with VS 2008 and VS 2010 still working fine.
You're probably better off doing it some other way than reading back memory from the card. Aside from totally botching your frame rate the z buffer values are not directly usable. AFAIK the z value is not stored linearly.

Targetting older stuff first is seconded. The 6502 instruction set is also very similar to its successor, the 6510, which was used in the C64. There's plenty of material out there giving you a glimpse of what to expect.
