You want 0 Accuracy rating as a Jugg Tank, it's merely wasted itemization that takes the place of tank stats (shield, defense, and absorb)
Essentially the only stats that you need to focus on are Defense, Shield, and Absorb.
Check out my Jugg's current gear set-up for a better idea (http://swtor.askmrrobot.com/character/1398e78c-d2d7-40bb-bd06-1b62cae5d1bf)
The ideal distribution for your tank stats is 27% defense, 50% shield, 55% absorb. This is only really achievable with fully itemized/augmented Campaign gear. For now, just focus on getting your defense to 27%.

EDIT: Just re-read your post and noticed you said you are using strength augments. That's a big no-no, replace those with defense or absorb augments. It's not a tank's responsibility to push damage on a boss, it's a tanks responsibility to mitigate as much damage as possible. Let your DPS focus on damage, if you're hitting enrage timers, that's their fault not yours.
