My first shop was 11' x 18', When I built my current shop I wondered how I would fill the 22' x 24' space, now I wonder how I fit all the stuff I have in it!
I would play with the Grizzly tool it works great. How you work is important to how you will lay it out. I set up my shop in a circular pattern. I have my chopsaw and bandsaw near each other, to rough out material, then jointer is near them, followed by planer, they kind of go around the tablesaw, which holds all of the pieces while I do the surfacing. So think about how you work and and lay your tools out in that order.
Also when I built my shop I ran power and dust collection under the slab, In my first shop I was tripping on the DC hose, and wish I had done another location as well. If you do this, which I think you should, make a little recessed box that you can put a lid over with the power and DC port in it.
I also did radiant floor in my shop that was another great choice.
I also put outlets every 4' in my shop a 110V and a 220V. I put these 50" above the floor a good height, above benches, and you don't need to bend over to plug things in, you may want to have some in the ceiling also.
