For mounting I just use drywall screws directly into the spoilboard but occasionally use small homemade clamps. When the screws are flush with the top of the work piece I never have to be concerned with hitting a clamp with the bit.

I home the machine each time I start it and X0 Y0 is different for each job so it wouldn't do me much good to have a fixed position for that. I also move pieces all over the table to help distribute wear on the moving parts.

Here are the simple L brackets with dowels and a piece I'll cut later today with the center already marked. The brackets are not fastened or pressed down when this photo was taken.

Yea... those L's really save the day at times. Like today I cut a rectangle acrylic w/ rounded ends.
I thought vinyl was for the lettering, my boss thought I was cutting it out. Guess who wins.
So I made a small jig to take the rounded end on left/bottom sides and cut away. Worked great.
