HA mine has 2 output jacks, one on the lower wing like the rx10d, which was already on the body, and i made a "strat" style angled one on the upper wing, like most rhoads have, because having the wire stick out from the lower wing is damn annoying when you're sitting down. i can come up with some wicked wiring ideas with this ... -)
for changing trem (or trem parts) it's really not difficult at all, the most "difficult" thing is to pull out the bushings for the mounting posts (where they screw in) out of the body and put the new ones in. You HAVE to change them, because Schaller, and most "licensed under" posts are narrower than original Floyd ones, it will fit but it will put much more tension at the center of the "knife edges" on the baseplate. The real ones are better made and much more precise to adjust anyways.
To pull them out, i usually screw the mounting post in, cover it with a cloth so i won't damage it, and carefully pull it out with a hammer's "nail pulling" end, with my other hand between the hammer head and the guitar body. And to put new ones in, i take a piece of wood about the size of a pencil, but larger so it won't get stuck in the bushing, then use it to -gently- hammer the bushing into place.
