you can go to almost maxed skinning knowledge in few hour now. just after you get the weekly quest for skinning after that do a relog so the system can activate knowledge points again for you. after getting weekly ones you should be able to get 100+ of these with the way i said.
buy few skinning tools from AH
try to buy deftness and finnese stats
remember just dont get bait knowledeg skills just the other 2 windows.
