One thing you have to be a bit careful of is that the starboard jib sheet (and sometimes even the port one if the jib's really flapping) can easily foul on the mainsail halyard cleat. I don't have a great trick for keeping it clear of that, but if you get the release timing right (and have a little tension on the leeward sheet as you release the windward sheet), it usually doesn't get caught.
The easiest way to keep jib sheets from getting caught on things on the mast is to screw a little stainless strap onto the front of the mast, one or two feet up from the bottom. Tie the middle of a shockcord to the strap and run each end down to the ends of the main beam on each side and tie off to the beam with a clove hitch at each end. The shock cord in that triangle configuration helps keep lines from catching on any projections on the mast.
