Ignore the "go go go" people, make a macro of what marks mean and tell people to wait for you to say "go".
Mark mobs, get CC up, go tank, and you'll be fine.
Gear suggestion: You don't need hit and expertise; don't reforge FOR these, get rid of them for mastery (if none on the gear) else parry or dodge (and keep those roughly even).
About the gun: I'm still using the one you've got; you can get an engineering-crafted piece with a gemslot which is marginally better for a few thousand gold, or hold out for the 359 BoE gun (I picked one of those up cheap, but decided to triple my money on the AH instead of equipping it... but then, I'm not raiding lately).
Trinkets: The green trinket may be 318 but it's an awesome piece; keep it probably until you get the dodge trinket from heroic Throne of the Tides (and reforge a chunk of the dodge to mastery on that).
