If I were doing it on a vacuum table, I'd try to locate the holes over a high point on a grid.

Not indexing? Remove the pins.

I can also see where a stratically placed pin could help a lot on a part that might be prone to shift.
I do this also, but first I cut a 3/4" hole and glue in a hard maple plug, then cut the 3/8" hole in the maple plug for the pin. The hard maple hold its integrity a lot longer than the MDF (holes in MDF quickly enlarged and the pin was sloppy).

First, I not only laughed out loud at a few of these I've also done them. Nice scar on my wrist from not realizing I had a bit in - those dust boots are very opaque. Had a project get thinner and thinner (twice).

Also--

When you first get the machine make sure you have dust collection before surfacing your spoilboard or your shop is useless for weeks.

When drilling holes through the table to attach the spoilboard make sure you use a good reference point and Save that Cut File with a very clear name so after destroying your first spoilboard you can make another one easily.

Immediately make a backup of your WinCNC folder because you'll be awfully tempted to customize macros and you don't know what you're doing.

Keep soft limits on as a rule so your machine doesn't sit there whapping when you forget to zero it to your stock. This will also increase the life of your spoilboard substantially.

Make sure you've rounded up everything you need to get your new machine inside before it rains all night.

If the shop fills up with smoke check the dust collector as well.

Never put your arm between Machine and lift truck on a decline while lifting the CNC
