477816 Flash replacement/items to make website mobile friendly

I am looking at making a website more mobile friendly, and I know nothing about how to approach this. It has a Flash banner on the home page, and I would like options on what to replace this with to function like it does now whether it's with Javascript or whatever else replaces Flash. Also, there is a jQuery slideshow that appears as it should on some mobile browsers, but not all. The final part of this project is to basically look through the site and suggesting how to make the site mobile friendly without sacrificing how it looks and functions on non-mobile browsers. So in recap- 1. Flash replacement for banner that functions and looks the same 2. Fix jQuery slideshow to appear the same on both mobile and non-mobile browsers. 3. Analyze website and make mobile friendly without sacrificing appearance or functionality. Site in question in genevabeachresort.com.
