I found that this is the best format for levels 1-15.
Do every quest, sell everything that you dont need.
At level 6 enter pvp for about an hour. It is the fastest way to level to 10 at this point. Unless you hate pvp, then just carry on as normal.
At level 10 you can pick up the professions quest. Run ahead to the town that gives you this quest and select two gathering proffs. Not that the AH prices are very profitable right now, but at least you are gathering some mats while you level. Store them in your bank to either craft with later, or sell at a much later point when the prices pick up. Either way you are saving money and time.
Then get back to where you left off at level 6 and start those quests. The mobs will be completely easy mode and you will be aoe pulling packs for days. So you actually end up reaching the level 10 quest hub at about the same time you would have even if you didn't do the pvp. Reaching level 10 in pvp and getting the proffs also means that you dont miss out on all those gathering nodes in the 6-10 questing areas.
NEVER repair your gear, no piece of leveling gear will "break" before you find an upgrade for it from a later quest. You will just waste money.
Try to only buy abilities that you are going to use immediately. If you plan to make an off spec, then the money that you earn in the 15 - 22 area is far higher and will allow you to buy those abilities easily. Wasting money on them early, will prevent you from having the 11g it takes to buy a mount.
Next keep pushing through the last level before going to the main city, even if you are already level 15. Finish every quest in this zone as the money rewards will help you to reach your 11g mount.
Hit the main city, do the housing quest and go to your house for the first time. DO NOT spend 1g to build a house. Leave it in the foundation state. Instead, open your crate and place all of the decorations that you have. just out in the open. You still get the rested benefit this way.
Go back to main city and collect and finish any of the quests that introduce you to the city. Usually some kind of hologram finding quest. Do a challenge or two if you can manage it. Do the rune crafting quest. Buy your mount.
Once all of that is done, head to the next area. 15 - 22. This area will take you from 0g back up to 10g in a matter of 1 or 2 hours tops. The quest rewards are much more profitable, so only start to buy offspec abilities at this point.
if all goes well, you shouldn't hit a bottle neck at any point.
