Personally, I don't think you should just jump in and MultiBox Eve.
I'd say play the game for a month, or two, or three, trying out different things, learning *some* of the quirks and then see if MBing fits into what you want to do.

I've played the game on and off since 2006 and only started MBing after knocking WoW on the head 18m ago.
I now run a 6-box PVE team running anomolies / scan sites in null and a 9-box mining team in null.
I don't PVP at all - it just doesn't interest me - so I consider myself very lucky to be in the Indy Wing of a Corp in a nice big Alliance.

Best tips I can give:

  • don't assume that you're safe in HiSec
  • don't fly anything you can't afford to replace
  • your default position should be that everyone is out to scam and/or gank you - as they probably are!
  • turn off the Local channel when you're in Jita
