Just a little tip if you want to level up your gathering classes. Get Botanist to level 25 as the first thing you do. This will earn you the ability "Sweat of Brow". This ability can be used by all the gathering classes and when it activates you will get 50% more XP when gathering. This can help you a lot and getting to 25 will not be hard and is definitely worth it.

(and now a plug: check out www.disciplesoftheland.com/maps.aspx for gathering locations).
