Can tell ya where to spend them, but I can tell you where NOT to spend them.
Do not spend training points on melee skill ups.
Your BS may be low, but just hang out while /LFG near groups and offer to BS mobs while waiting for a group. It will come up fast and free.
At your level BS is low because your just exiting that era where you probably were main tanking mobs or soloing. Trust me that changes.
I used my points to put the first point in languages, trade skills and about 40 points into Poison Making to get me through that rough spot between 170 to 210.
