Ive always used a chop saw with an abrasive wheel to cut, but I wonder if the cold saw blade would be nicer on the steel. As far as notching I use a bridgeport milling machine with roughing end mills like AFC357 said, I bought a few of every size of tubing I use, I really dont know how anyone builds a car without some serious machine shop work.
