Take a look at Goodyear Eagle NRG herringbone belts and matching pulleys. http://www.goodyearep.com/ProductsDetail.aspx?id=3400
Most radial bearings will accept a certain thrust, moreso if they are angular contact type, so you might not need a thrust bearing in your drive system.
For simplicity, look at flange and pillow block mounted bearings.

I've decided to use timing pulley's/belts or sprockets and chain along with captured roller/thrust bearings but am having a tough time sourcing them. I wouldn't be opposed to a gear reduction either provided a "bullet proof" reputation. The motor of choice is the ME0907 for it's lack of brushes, performance, and affordability. By my calc's a 2:1 to 2.5:1 reduction will be needed to maximize performance. Any ideas would be appreciated.
