I would keep your spec as is, with only the following possible options to consider:
- If you have pet management problems, you may want to drop points in UF to top off Improved Tracking, get Survival Instincts, and to top off ISS (since you are not using Aimed Shot, you are doing 3-4 steadies per Chimera cycle and ISS proc uses not only result in more damage but a mana savings too). The choice here is preferrential depending on which you prefer per your playing style.

My only other suggestion is to drop the Viper glyph. It doesn't seem worth it to me, even for 10-mans. With not doing Aimed Shot at all, having Aspect Mastery, and having the T7 4-set bonus, I would think that your mana regen during Viper is sufficient and your DPS loss is not that much that you do not really need teh additional 10% mana gain from it. I would suggest using Steady Shot, Serpent Sting, and IAotH glyphs.

In addition, you didn't say what elixers/flasks you are using. If you are having mana problems and am not dieing a lot, I would not suggest using a flask. Instead, I would use two elixers with my choices being Mighty Agility and Mighty Thoughts. This combination has almost equivalent DPS to the Endless Rage flask but also increases your mana pool by about 700-775 depending on whether you have BoK (assuming you had both BoM and BoK since two pallies) and increases your mana regen while in Viper. Mighty Mageblood is another option for the guardian elixer, but I prefer Mighty Thoughts due to the DPS boost.
