it might take awhile, but buy the ilvl 232 t9 pieces. helm, chest, gloves, and shoulders should let you move away from most of that naxx gear, which looks like whats holding you back.
drop some gold for a nobles deck to replace that pvp trinket your wearing. unless you are running totc 25 every week trying to get death's choice, you wont replace it. when youre in a naxx25 and grim toll drops, snatch it up. even with the nerf to arp, its still the best stat for arms warriors.
im guessing your legs are a new addition since you have 2/2 weapon mastery and sitting at 26 expertise from gear. you should take those points out and move them over to imp execute. paired with the execute glyph, you get 40 rage executes and only use 15 rage for it.
