Welcome. Are you from Sweden or just Swedish in nationality?
From my experience, RMVX/Ace seems more friendly towards newer people while XP, though slightly older, is a bit harder to use but feature wise, I think XP is much better and especially better in mapping. I have not tried MV yet, but people are saying it is good. For me, I toy around with VXAce for more simpler types of games while my main projects are handled by XP.
There are plenty of tutorials around this boards I think, which can help, but many links to some demos are unfortunately dead. You can always just ask around here I guess.
