If you do a pulley system, be sure to include safety chains in case you lose your grip or the rope(s) comes loose. I would have several ropes, rather than a single one. Tie the ropes together like you do with mini-blinds, you know like when you pull on the strings you want the blind to go up straight rather than crooked. Same principle for your lighting rack.
Having access from several angles is a good idea. If you can't reach it, you won't deal with it.
