CP angle doesn't affect the way the controls operate as much as it does how long you can play them.
If your CP angle is too steep, it forces your wrists to bend too far, and starts to hurt after awhile.
I played around with some different angles, and decided 5 degrees was good for me.
Most of the arcade CPs are a little steeper than that, but my CP didn't feel right to me.
I would suggest that you build a simple standalone first.
(Basically just screw a board across two angle cut uprights).
Once you have that done, tilt it up/down using books and magazines, until you find the angle that is correct for YOU.
I highly recommend building your cabinet to fit you, for anyone building their own cabinet.
I experimented with all kinds of different angles, heights, depths, etc... and then built my cabinet to fit ME perfectly.
Let everyone else adjust to your preferences, rather than you adjusting to whatever measurements the OEM cabinets were built to.
Alot of the arcade cabinets had the CP set too low for me, so that they could accomodate shorter (younger) players.
As far as the yoke CP goes, it needs to be shallow enough that you can hit the bottom of the rotation with the handles, but steep enough to let you hit the top of the rotation.
I don't really have a magic number, and think that it may vary depending on whether it is an original, or an aftermarket yoke.
If you get it too steep, or too shallow, you are going to have to really contort yourself to hit the extremes on the handle rotation.
