Another thought was to finish questing in WPL, EPL and possibly Silithis, go to Outlands, finish all the regular quests there for all the great gear then come back and do all the level 60 instances. Any thoughts?
Winterspring and Felwood are also good places to quest along with WPL and EPL ( skipped Silithus).
That and BRD (lots of quests there) is what I did from 51-58.

Entered portal as soon as I hit 58, did some quests to gear my group and I was 60 before I could notice (58-60 is REALLY fast doing outlands quests: both quests and mob gives insane xp compared to required xp by those levels).

Cleared ramps at 60 (4 grounding totems makes Vazruden pretty simple, not sure about about a regular setup ), BF at 61 and working on SP as of now (lvl 62).

If you really want to go back to old world instances, I would recommend doing so after you get some outlands gear. But keep in mind that TBC instances are more challenging, give more xp and cash.
