I highly recommend actually staying in the 20-60 range zones until you ding 62. The reason for this is that despite getting a slight penalty in experience for being over-level, the advantage of having flight will more than offset this. That, and WOTLK and TBC zones are the slowest part of the leveling process. Minimizing your time there as much as possible is worthwhile.
Patch 5.3, like all new updates, is attracting a throng of returning players, many of which will be undergeared and willing to spend Gold to catch up with the rest. While the profits might not be as lucrative as with the new items, there may be less competition here. The key here is scanning the market for in-demand leveling gear and producing the right amount to avoid getting stuck with an unsellable stack of outdated items.
In recent weeks, players have been giving Blizzard an earful concerning experience gains and leveling in World of Warcraft. It looks like a couple of issues are at the heart of these problems, including time to kill certain baddies and the time it takes to level up between levels 60 and 80. While Blizzard is still trying to figure out why some baddies are taking too long to kill, the hope is that a hotfix launched this week will address the problem of leveling.
Special mention is the Darkmoon Faire Top Hat and WHEE! buff. While not always available due to the DMF being inaccessible most of the month, if you happen to be leveling when the DMF is running, it might be worth your time to go and get these. AFAIK they do stack with heirlooms, although I have not personally tested it. Fair warning: These buffs do NOT stack with each other, and the hats disappear after the DMF goes away later in the month(unless you only log in when the faire is running).
In addition, you'll want to pick up leg and shoulder enchants and have them in your bags. These enchants have a level requirement of 80/85, but can't be placed on items above iLVL 136. You can get around this by having a level 85-100 character apply the enchant before mailing it to the character you're leveling, thus getting use of the enchants before level 85.
Something to keep in mind as well is that this will make enchanting materials more valuable, since it is likely most players will now simply scrap their boe greens instead of getting them disenchanted. Also redundant dungeon/raid gear can be scrapped rather than traded to the (guild) enchanter in the run. Less stuff gets disenchanted, meaning there will be less ecnhanting materials, meaning their value will rise. All the more reason to DE rather than scrap as an ecnhanter.
