Manhandling jCarousel

Question

Hey Folks

I want to configure jcarousel for use on a voting site. The idea is that 2 panels slide into view, the user clicks their choice, the 2 panels slide out and 2 more slide into view. until now i've never tried this level of customization and its pretty daunting. my jquery level is modest at best. thus far ive got the visual side of things more or less ok.

So I guesss I now need to know these things..

1. how do I apply the NEXT button functions to the panels themselves? (I do not want to have 'next' / 'prev' buttons)
2. once the user click on their choice I would want some kind of user feedback (eg. a messgae) before the next two slides appaear.
   Hows is this achieved - is it a 'callbacks'?

If someone could point me in the right direction that would be great.
