In my libraries I use a separate mechanical layer for footprint origins. I mark the origin of the footprint with an X symbol, where the cross of the lines sits exactly at the footprint origin (coordinates 0,0). That could be eventually useful to the assembly people as well.
Apart from that I don't think you normally need any other information in the footprint, such as measurements and coordinate labels.
