What Brista said. Go Herbalism/Alchemy first until you hit 35. Low to mid-level herbs are hard to come by in the auction house. Collect all cloth (Wool, Silk) you find in the meantime and store it on the bank. Then, at 35, drop Herbalism and learn Tailoring. Use up all the cloth you've find so far to level up Tailoring. Buy the rest of the cloth from the auction house and/or use your level 58 to fill any cloth "gaps", i.e. Mageweave and Runecloth. To level up Alchemy further (275 is needed for Arcanite Bar), buy the mid- to high-level herbs in the auction house. Always look for the least expensive way to level up. This will probably the most expensive part because high-end herbs aren't offered in droves either.
While we are on the topic of profession twinks: My level 40 Warlock, an Enchanter (and Tailor) twink, has just hit skill level 290 (Arcanite Rod), and boy, that was REALLY expensive ;) Twinking Alchemy and Tailoring was a cakewalk compared to that. I suppose that it will cost me yet another 100-150 gold to get to level 300. Those Greater Eternal Essences and Small Brilliant Shards burn your cash in no time.
