Yes, you should be able to get the patterns from him and complete the other portions of this quest (unless for some reason it is broken, if you try again and he still won't give you the other patterns you can /bug report or try /petition). It is good starting armor for a ranger, unless you are lucky enough to have some pp to buy some other gear. If not, complete this quest, and then you can work on the Ivy Etched Armor Quest as an upgrade to Trueshot.
