At your content level don't worry about bonuses outside of maybe the 2pc. Maximize your effective health. Collect 95 badges and get the Cata chest, then get the Kraken gloves next (they are superior until the heroic version of yours). Don't buy the tier legs, get Pillars of Might instead.
Now to further help you. Drop all gems but the ones in your helm for 30/51 stamina. Next, enchant your shoulder with 30stam/15 resil, chest with 275 hp, weapon with blood draining and gloves with 240 armor. Personally I'd take the points out of focused rage and fill up shield spec and imp disciplines, or only put 2 in shield spec, 2 in imp disc and 0 in focused rage, up to you. Glyph of sunder is bad, use shield wall and last stand + devastate and switch in taunt when you need it to land for different fights.
