Question installing sub panel for garage

I am planning to replace the main panel in my home in the near future. Currently it is all still fuses, crazy.
I'm thinking a 100-125A panel, and I would like to run a sub panel to the garage. The garage currently only has one outlet on it right now, it is an attached garage.
My idea is to wire the entire garage with outlets, and also have a 220V for my air compressor. I would guess 8 circuits would be plenty for the garage, 2 of which would be on the air compressor and the remaining for outlets, maybe a spare or two.

What I'm wondering is, can I run from my main panel in the house a Romex, maybe 8-2 from a breaker out to run the sub panel in the garage?

No, an 8-2 is good for either all 240 volt circuits or all 120 volt circuits. If you want a typical 120/240 volt subpanel the 8-2 has no neutral. At the very least you need to run 8-3 or better yet, 6-3 NM-B cable (aka Romex).
