Mace Spec.Follow

hey i was wondering if their were any mace spec rogues around that might give me some advice, even combat rogues, i have never really spec'd into combat, i use to be hemo mace, and then i spec'd to mutilate and love it but i am slowly creeping towards getting the first of the hammersmith epic maces so id like a build that would compliment it.

ive also started running arena and hopefully have drake mace and glad OH mace at about the same time.. im a enchanter/blacksmith so progress is slow due to the lack of mining and gold from buying mats.

i threw together a build first time ive really looked at the combat tree so some of it could be wrong, build is for pve and pvp, well i hope.

i could also completely forget about mace spec and still spec combat, or i could go back to hemo but ive been hearing a lot about how hemo is really lacking since BC.

i was also wondering how important combat rogues feel that parry talent is, and i took vile poisons cuz i really find eviscrate lacking in dmg compared to envemon, gouge i rarely use anymore, ill use it to stop a spell cast if kick or other stuns are on CD, but im still not sure on it maybe evisc will be better now that i wont be able to CB envenom..

well i know its kind of early to be reading a page full but i would really appreicate advice, comments, and suggestions anything is better then nothing.
thanks for your time.
