If you're trying to avoid collect quests, you'll have to cherry-pick from the various zones for best results. I'd recommend turning in turtle meat and doing kill x quests in Southshore, then kill x quests in Arathi. You might be able to pull off Stromgarde stuff in your low to mid 30s as well, and the quest rewards are very nice there, xp-wise. After that, you can do either a couple in Alterac or head to Badlands, where you can get some nice xp doing turnins and quickies at 35+. This keeps you away from Kalimdor, minimizing your travel time. YMMV of course.
