Order of events doesn't matter. It's probably easier, though, to pre-flash and then make the print. The other thing with pre-flashing is that if you always do it the same way then the necessary pre-flash exposure will be the same for that grade and type of paper. For instance, if you put the enlarger head at the top of the column and stick with, say, f16, with no negative in the carrier, you'll only need to work out the flashing exposure once.
