Everyone's going to tell you not to crime, or fight, or mug and just train train train; personally I wouldn't listen to them if you plan on leveling up. If you do what they say you will have the best stats for your level, but that's only useful if you're going to be a runner (person who carries cheaper NJ items to Putnam/AZ for higher levels for ca$h) so no one can mug them, and I think this game has enough runners.

Make training your priority, but don't obsess over it, because the game will become very boring for you.

Also expanding your cell should be a priority as well, if you can't buy favors, use the voting links to get 3 free ones a day, and do surveys to get more (check the Prison Yard forum for my tutorial on them) then upgrade your cell, it'll take a while that way but you'll need it.
