would this be a good setup for my revo? (info/screenshot)

Since you are using a decently high voltage, I would use a Neu 1512 2.5d (kv=2000) for the high end, or a 9XL as an inexpensive option. Then, just gear up a tad. To help keep the pinion size to a more manageable level, you might want to consider using the wide-ratio gear set.

By the way, you can use the "Export Values" button and copy/paste the text into the post, like this:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 2.111111111111111
Additional Ratio: 1
Spur Tooth Count: 38
Pinion Tooth Count: 18
Battery Voltage: 18.5
Motor KV: 2000
Tire Diameter: 4.5
