Couple of things.. What's MOAG and MMOAG? What's the difference between off axis guiding and off axis guiding? Three inch focussers? I can only find 2 and a half max at Moonlight.

MOAG = Manual Off Axis Guider. MMOAG = Monster Manual Off Axis Guider.

The monster MOAG is bigger and designed for bigger sensors. I always think to the future now for purchases. Is this purchase going to be transferrable to another system of better quality? If yes then you are on the right path.
A 2.5" focusor would be ok, but not ideal for that scope. It would work fine with smaller sensors but would be too narrow for larger sensors. In that case you would need to go to a larger focusor.
Depending on budget, you might have to compromise on camera but your focusor and OAG guider are holding things up in the air. You need to have a beefy focusor with autofocus ability. You could use a QHY larger format camera and save some money there too.
Bottom line is if you scrimp on these components you will be buying problems for yourself.
