I'm gonna side with ohmikeghod on this one. Both while you are leveling and when you max out, gathering professions make you the money.
Your skinning is a good choice for a hunter, since you can continue to use your track beast, etc.
If you think you might like to chill out at the AH a bit each day, disenchanting is good.
Even though tracking minerals or herbs means you turn off your other tracking, hunters can be herbalists and/or miners (it's a personal choice). Those professions make plenty, although minerals probably sell better in the AH at a low level.
What would I do? I'd lose the leatherworking, pick up another moneymaker, and buy an occasional crafted item rather than making my own. When you hit 70, if there is some epic gear you want to make, you will have the cash to start crafting.
