Hi Lee
Ok,It can be confusing so you need to take things one at a time dude.
1:center focuser (use a high quality laser)
2:center secondary to focuser
3:center main mirror to secondary
Ok basics over, now,looking at the second pic looks to me like the spacing of the coma correcter is good.....center right side of the image tells me this.
Top left and top right tell me you have tilt in the focuser.....this should be the first thing to take care of....center focuser before collimation of mirrors otherwise everything else is a compromise.
I see in the bottom right that you have field rotation.....PA dude otherwise It will confuse you.
