Sounds like it's been pretty much sorted I guess. I'd do it differently personally, but that's just me. I don't like PODs or big samplers though. I'd use two bass rigs, one for bass and one for high gain/weird effects (this is what I do actually) and then use a Jamman for triggering samples.
Digitech Jamman is small, compact, cheap, self contained, doesn't require a big board of pedals and you can load samples really easily via USB. Mono only though, speaking as a live sound engineer though, I tend to run everything mono FOH anyway unless I get a really insistent keyboard player or something.
