drawing circles on an angled piece in AutoCAD 2012 in 3D

I am trying to draw a circle on an angled face on a valve I made, and am not too sure of the best way to do it. Here are some screenshots:

 

 

Here is a front view showing the angle. I need to use the face at the top that is on a 22* angle or so

Here is a top view showing the 10 holes I need to make at the proper angle. The blue lines are showing where each of my holes will need to be with a fitting on it as well

Any help will be greatly appreciated, let me know if you need any different screenshots

You need to rotate the UCS.  Use the UCS command, 3 point option, pick the quadrant at 3 o'clock on the large circle, then pick to show the X direction, then pick the quadrant at 3 o'clock on the smaller circle.

If it were me, draw a line at quadrrant from each circle to get the angle then UCS, use object

after draw 1 then polar array.
