Road Wheels & Road Wheel Recommendations?

Thanks. I'm thinking 19mm on the front for aero, and 25mm rear for rolling resistance. Probably with a butex or latyl tube in the back.

Depends upon the rims, wheels etc. If you want to use 19mm tires you should select a rim, resp. wheel, that is designed for 19mm tires. With a lot of wheels there is no advantage and in racing conditions its often better to go wider--- I've even done 25mm front and 23mm rear.
As to inner-tube? If its for performance.. then Latex. Nothing wrong with Butex (I use a lot of Conti tubulars) but thin high TPI count tires and a latex inner-tube ....
