OK so 3 things
1 with ZOD go for MM, since you have around 500 ArP
2 if you are still uncertain use
www.femaledwarf.com
3 gem ArP when you have over 800 pasive ArP
OK now I saw talents so :
Improve arcane shot, move all 3 of them into improved hunter's mark
You are not hit caped so move 1 point from improved steady shot into Focused Aim
if you are doing mainly 10 mans I would recommend the other 2 points from ISS into Rapid recuperation, else move at least 1 point there
Glyphs -
Glyph of aimed shot replace with glyph of serpent ting
Glyph of kill shot replace with glyph of the hawk
And also put gems in all your gear
If you have any other questions fell free to ask
Good luck
Also try to read some more info from here
