As for the vocal processor... We still have the Roland VP770 and the VP7. We only use them for bigger shows. My wife and I have been doing a few smaller gigs and some non-pay gigs. The Bologna Fest was a non-pay show without much set-up time built in... no extra harmonizer for them!!

We use mostly lyric sheets or chord charts that we create. I have the sheets in front of me in the order of the show that we planned out. BUT we are currently turning those sheets into PDF files in order to load them into our iPads. We play in church every Sunday for a contemporary service but our gigs only number 8-14 per year without advertising. So, paper is fine for us right now and will always be our backup.
