One of the best places anywhere to get information is the Mileage Run Forum
Begin with reading the Mileage Runs...A Primer! thread first as everything you need to know on putting together a mileage run is there except a CRS.
I make it a point to check the Mileage Run Forum almost every time I log on to FT as fares constantly change and the posters to mileage run seem to know about it before anyone else.
