1) While it's kind of cute, it's not going to earn a lot of responses outside of "yes". You could post your question in the form of an full sentence, inside the actual post. Though, honestly it doesn't really matter.
2) Wrong forum, I'm going to move this when it's done. There's also a bunch of threads on this already, that if you had searched just "vista" you would have found.
3) Yes. RMXP works on Vista if you are set to an admin. I don't know if you need more, but that's enough if memory serves me correctly. RMVX will be released in English I believe around February from the last thing I read. That will, likewise, work on Vista.
Have a good one.
