I like to use a couple of turns of electrical tape and a drop of super glue to prevent the braid from spinning on the spool... and like others have said:
When I re-spool, I'll leave about 1/3 of the old braid on the reel... cut it cleanly as possible... and tie the new braid onto it using a double uni-knot.
I too use a fluorocarbon or monofilament leader depending on whether I want the leader to float freely or sink based on the lure or presentation.
