Well, I have a good bit of experience with flash (ActionScript 3) and javascript (but would not consider myself a true 'pro'), and I say you are definitely on the right thought process when you consider flash. Browser implementations of DOM are slow and cumbersome when attempting heavy/multiple animations, and that's not only true of IE but others as well, it's just that IE would be ranked worst in most cases. Lighter stuff, sure fine, javascript can handle some. There is also Java, which I have barely tinkered with. But I personally don't like the browser java plugins. So flash would be my choice. Mouse and keyboard support is not an issue, both can be used actually with a bit easier support than via javascript as js has some differences between browsers. Whereas flash operates in it's own runtime environment, so cross browser bs doesn't come in to play. So my vote is for flash! Buckle down, learn ActionScript 3 [help.adobe.com] and have fun!
