Your gear is fine for naxx 10, maly 10, and heroics. I recommend continuing to gather emblems and get all or most of your conquest/valor gear. Then you should be more than ready for Ulduar 10. Also I recommend replacing your offering of sacrifice with essence of gossamer.
Your question is oddly worded, but if you are asking "When can I tank Ulduar 10" a common test is the "Ignis (pre-nerf) check". Go through your gear and make sure you have full Ilvl 200 gear. In addition to the Ilvl 200 gear you should have a smattering of 213 / 219 / 226 gear (3-5 pieces). Tanking 10 man TOC would presumably follow a similar pattern. All 219 gear, and maybe a few pieces above 219.
