My gear was probably worse when I first started Kara & I used many similar blues. Only one's I'd suggest are the KOT legs if you can get the rep as it's a massive amount of stam you can pack onto to them. Only part I'd be worried about is having to use +def gems to roll over the cap, as +hit or +dodge would probably help you more skimming the stats, and the bracers would be a cheap tweak.
I used mine like that until splashing out on some Green fortress ones for the extra stam for the harder bosses. I mention the +hit as 20 seems pretty low and a few misses or dps crits could be painful. If you are lucky with the first few boss drops then you'd be laughing as the bracers and belt would be a massive boost to you. Something like the heroic ramps belt would serve you well over what you have.
