Alacrity isn't really a useful stat, but those two are probably even less useful since you have no shield.
I mean, if you're still leveling, and it's an upgrade on the other stats from what you had, then sure, but once you get into endgame gear, it will get you chewed out and even kicked from some flashpoint groups.
And I have no clue about the chest and legs. What level, stats, green/blue/orange?
Chest is Orange and requires level 43. Legging is orange and requires level 43. Do you know any gear with good stats?
