I usually use wow-professions.com
it's got lists of all the mats and i find it helpful, you might not :)

once you hit the the upper 300's - 400 range of JC it really helps to have a alt thats a alchemist. you can make skyflare diamonds up with no cooldown then cut them and dump them for around 20-25 points.

I did a combo leveling of mining/jc all at once so it took me maybe a week for maybe 3-4 hours a night just running around looking for the lower nodes at first, then prospecting the ores for gems to cut. At that point just buy up a bunch of the midrange gems or make a few of the blues up that are cheap on materials and send them to a enchanter to DE for extra shards. Basically I went and got what I needed myself and hit the AH for fill in materials as needed when I just wanted to powerlevel through it. Problem though is once you hit 450 to get the epic cuts you'll need to start doing the daily for the tokens to buy said cuts, unless you want to eat up mass quantities of titanium ores for the attempt at the powders to buy the tokens. It's not a guarantee of each prospect of 5 ores yields a powder.
