This is just silly. You want your Blade Rush spam to crit as much as possible. Any Sentinel (no matter what spec) needs to have at least 350 crit rating (don't go over 400, try to to be at 375). 22% is a bit on the low side.
Either way, when you start getting Columi/Rakata, the gear will take care of your stats anyway. You're going to have to replace those ungoldy +acc mods with crit/surge/power ones, but that's all you really need to do as far as stat juggling goes. I'm at 98.1% (108.1%) acc right now with 0 points in Steadfast.
