Escort quests can take awhile to do. I have thoroughly tested all the escort quests in the game for time/xp. Most are worth doing, but as long as you are able to actually do them without failing. Most require you to pay special attention to the escortee as most are fragile and will die easily, so do your best to keep mobs off of the escortee during escort quests. The longest one in the game is the Tanaris chicken escort. The chicken escorts are only worth doing if you were able to do all 3 of them, as if you do, you will be able to turn in an additional easy quick XP turn in quest at BB, which makes them worth it.
If possible, avoid purchasing Gear from the Auction House - Ideally, you should be able to achieve level 60 without buying anything from the Auction House. This way you will save Gold, but possibly make leveling a bit harder for yourself. If you badly require an Item upgrade, and the suitable Item is available on the Auction House for a low enough price - buy it, but only if you think that the investment will pay for itself in one way or another (the main exceptions to the Auction House ban Rule are Weapons and Wands, as they make leveling much faster, and pay for themselves by allowing you to chain-kill more mobs without Eating and Drinking, which saves Gold and time).
Acidmaw Bears, Grizzlies, and Maulers (marked BLUE on the map) - The once majestic Bears of Felwood are now corrupted by Fel Magic. Free them from their painful existence, and earn some Gold in the process. Felwood's Bear species drop a lot of Vendor Trash Items (Bear Jaw, Bear Flank, Savage Bear Claw, and Large Bear Bone), 14 Slot Bags, rare 16 Slot Bags, and most importantly can be Skinned for Thick Leather, Rugged Leather, Warbear Leather (used by Leatherworkers for Warbear Harness and Warbear Woolies Recipes), Thick Hide, and Rugged Hide (Skinning is recommended for this Farming Location, as it will greatly increase potential profits).
Check Item's Vendor Price before posting it on the Auction House - Selling items on the Auction House below their Vendor value is a common mistake. Avoid it like fire, and always make sure that you are not losing Gold on your Auctions. If you plan to sell an item on the AH for a price just a tiny bit higher than its Vendor value, you might be better off just vendoring the said item (this will allow you to avoid the risk of losing an Auction fee if your Item doesn't sell).
