You're free to take it slow or rush to the top, but generally, we advocate just aiming for lv95 first before anything else. Typically, any piece of gear below lv75 is worthless after lv78 (not everything, but most) and everything above lv75 is much easier to obtain at lv95/99.
By the time you reach lv95, you should have already found some decent gear on the AH, this may require farming. Also, take this time to raise your skills since they will fall behind. Once you have most of your useful spells, decent AH gear, near-capped skills, try to clear the final limit break quest. You'll need 3-4 others, but it's easy if you prepare for it.
Above all else though, find a linkshell.
