I chose hunting mainly for RP reasons. What should I put any lessons into it?

follow the guild scrolls, you should be fine after novicehood go for Knighthood up to spec then learn out yourspec. Maybe get a few of the hopeful skills like insomnia or clotting small minor things if your Guild help doesn't tell you to already. Really the hunting skill is useless untill you move into the spec I'd avoid it unless you have extra lessons to spend.
