I could use some advice as im a total n00b in BC instances.

I have just cleared Sethekk Halls, wuhu (normal lvl) and I was thinking about what I should try now. I only wiped a handfull of times (yes I suck sorry), always do to my tank being charmed.... wtf should I do about that? I healed through it, dps through it, but mostly I died when this happened.

Please bear in mind I have almost no expertise in instances.

I would like to know which instances you think I should hit now?

I've heard that shadow labyrinth suck because of fear. What would you suggest? Go for one of the lvl 70 instances?

Or would this be to hard?

I could just jump into some of the instance, but if some of them are really difficult to box, I would probably get frustrated and quit or something. So instead of enduring the pain of wiping all the time, I could use a pointer in the right direction.
