Can someone tell me how to get training stticks, and if i have to do a quest, wich one(s). :D

Go to shilo village and sell some gems to the shop, there are other ways but this is one of the most simple.

They are available throught the Grand Exchange for 34-38 gp presently.

 

 

 

Jogres also drop them occasionally.

 

 

 

Or you could always go do the Tai Bwo Wannai cleanup minigame.

If you take the fairy ring to Karamja ....code ckr...the same one that is close to the nature altar ...there are about 5 or 6 hobgoblins just north of the ring ...these drop trading sticks quite often when you kill them.
