IMHO good quality 32h rims should work fine..... 36 better
i think the unless you are riding bigger that 32mm tires at low pressures, tube is the way to go, less hassles in general. Some in goathead territory swear by tubeless even for smaller tires, but remember tubeless was to solve the pinch flat problem in big, low pressuer mountain bike tires
here is a set of 36h ultegra for $259
