Level 35 with only 105 herb...
Im pretty sure you can pick most of the herbs in hillsbrad. Thats prolly your best bet. Once you get a little higher try arathi for herbs. Although you should be over there leveling...

Just take an hour or two walk around hillsbrad and collect.

I 2nd the vote for Hillsbrad. Then move into Stranglethorn Vale.

Personally I liked Wetlands (until around 175), then Arathi/Alterac (Arathi for a variety of herbs, Alterac for less ganking and a great selection all to yourself), then into the higher zones (Hinterlands is good for a start, especially for Sungrass at lowerish levels, and then the lower areas of Azshara are nice). By your 50s, Un'goro rules all others, and then Winterspring in the late 50s is great.

Once you can pick Blindweed(I forgot the level required), you should be able to top out to 300 in under an hour in Swamp of Sorrows. At lvl 37 I went from not being able to pick Blindweed(a few points shy) up to 300 in about 50 minutes. Not to mention I had 4 stacks of Blindweed, that I dumped on the AH for 7.5Gold each and sold em all. Not bad money pre-level 40!
