I believe (but am not 100% certain) that all of the stats on blue gear (and High-quality crated gear) are already capped. You can only add stats that are not already present.
If you're talking about caps, something like "a character can't exceed 1000 crit total", there are none. You're only limited by the gear you wear.
EDIT-I forgot this, but skillspeed and spell speed do have a kind of cap, you can't go lower than a 1.5second recast timer. That's more skillspeed than you have available right now, I think.
