Definitely look into using jquery for this kind of thing, makes javascript and DOM coding so much easier. Having said that I think you might be better off doing a complete style sheet switch as it is much easier for you to manage rather than trying to change certain elements programatically.
I'd still go with jquery though and here's a page expalinging how to create a stylesheet switcher with it + stick it using cookies:
