I used this post:
http://www.blizzardguides.com/wow_alchemy_guide.html

It is a little outdated (you don't have to buy Superior Mana Potion and Major Healing Potion cause they are from vendors now), but for 1-300 i followed it 90% of the time. It does say this but says it like on the third page (if you print it out) from 105-110 make Elixir of Wisdom. Also all the herbs that you don't use save them until WotLK comes out. The new skill seems to be using herbs. So on the release date or the day before put all the herbs on the AH double or triple the price because people will pay for it. Specially the herbs from the starting area (peacebloom and silverleaf) cause they will probably need a lot of them to get to 1-60 (alchemy you need 60 of each) so you can probably sell a 4s peacebloom for 50s - 1g those days. If you are going to collect them then there isn't a problem yet (as soon as it hits people will be farming or about 1 month before the release). That is why i powered my guys now, cause i know the price will go up huge. Also when the expansion comes out probably 2 months later transmuting primal will not have a cool down, like most of the old world stuff. Blizzard will probably do this because not that many people will be farming the mats so they will go up in price. I will be dumping all my low lvl herbs that day.
