Currently showing as fishing pole equipped, but even without a weapon and shield your Defense is at 555, so you're well over the defense minimum.
That said, you should change your +20 defense gems. I'd suggest the following:
Helm - 10 defense/15 stamina or 10 hit/15 stamina, your choice.
Cloak - 30 stamina or 10 hit/15 stam (currently 20 hit)
Chest - 10 defense/15 stamina or 10hit/15 stamina.
Gloves - 30 stamina or 10 hit/15 stam, 10 defense/15 stam if you insist on having the +6 stam bonus.
Pants - 10 dodge/15 stamina instead of +16 dodge, or 10 expertise/15 stam, 10 agi/15 stam, again your choice, keep the stamina gem as is.
The only enchant that I could see being changed would be your gloves, if threat is not an issue for you then either +240 armor or +18 stamina would be better. 18 stam will help in physical intensive fights as well as magical fights, where as +240 armor only helps with physical fights.
For gear to aim for, if you're planning on ICC then pieces with high bonus armor on them are highly valuable.
