Assuming that this is your tank set, you need more armor and dodge. You are currently crit immune with resilience so defense rating is not an issue. Your health looks fine also.
I would consider getting the Braxxis Staff of Slumber and putting +35 agility on it. You can usualy find the staff in the AH for less than 100 gold, but the enchant is rather pricey.
Your cloak also needs an upgrade. I would get either the Bogstrok Cloak, that drops in Slave Pens or the Thoriumweave Cloak which drops in Mechanaar. Put a +12 agility enchant on the cloak. Also, as you mentioned, get the Clefthide boots.
You could also upgrade your necklace. I would pick up the Necklace of the Deep, and gem it with stamina gems. The Necklace is craftable and can be picked up in the AH for about 70 gold.
Also as far as gems go, +hit isn't really neccesary for a tank to have. I would spend more slots on agility or stamina than on +hit.
This is probably the easiest way that you could gear yourself with the fewest changes; however, it might be worth it to get in entire Clefthoof set and stack defense rather than resilience. Since defense also contributes to your dodge rating this might be an easier way to get your dodge up.
My armory link below also has some fairly easily obtainable gear.
