I don't know what people are trying to achieve with these posts... your gear is pretty poor, getting hit from gems is a poor source but necessary in your case. You still haven't reached the hit cap which is 289 by the way.
I suggest you read the spriest sticky in the priest forums and then research resources such as www.shadowpriest.com and www.elitistjerks.com and then if you have any questions that aren't addressed ask them.
this is the type of thread i guess you were looking for. Kinda useless here, no avatar to press and check the armory of the guy that just "rated" you. For all you can know he can be the best geared priest with all 'end-game' experiance, or a scrub that just got 80.
If your looking for true advice, whisper a well geared/top guild priest on your server priest and ask him for advice, not many would say "no" unless they are busy raiding. Visit www.elitistjerks.com (although, with all the respect, alot of whats written there is far from being good or true, but its still a nice start).
