I'd do 3 as well. Park em at 70, and save up a few quest turnins for when you activate wrath, so you get a decent exp boost when you first start. In the mean time, level up some alts. I have tons of random teams at various levels that I'm slowly leveling up via round robin rested exp swapping. If you had RAF, is it still going? That's the best time to level any toons you think you may want later, cause it gets even more expensive to try and do it again, either via transfers, or maintaining more accounts.

Also, what are you goals in the game? If you want to raid, or end game pvp, make saving money a priority. If you are just having fun, have fun with new toons and upgrade the last 3 accounts when you can.
