I think thats some pretty sound advice. Once you feel reaquanted you could get con groups easily as CNJ and hit 50 fairly fast. CNJ are always wanted.

I don't know what kind of gear you have, but you could even go out once you level up, and farm NMs for the 30-35 CNJ gear that will work well for you untill you do some DH runs. Then you can earn great gear doing DH and be a part of a little endgame fun. Or you can farm some cash and buy gear to be materia fitted.

You can also do some research in abilities and see if there are any other classes you may desire to level so one extent or another for support abilities for your playstyle.
