You have plenty of hit. I personally ran with 197 hit rating and had no rage problems whatsoever, at least in Karazhan (although with my new shoulders it's up to 210, and those gems are temporary, I swear! >_>)
What you need to focus on now is more AP and crit. If you check out the Fury guide here on TS), there's currently a mindset that you shouldn't gem for hit unless you are under 100. Given the amount of hit you have, you could easily afford to change some of those gems for crit or strength gems. Beyond that, I'm a bit out of my league, as my guild is in Kara, while yours is in SSC/TK. Keep at it and show everyone what a good DPS warrior can do =D.
