I'm a big fan of CS Unplugged. It's generally aimed at a slightly older age range, I think, but you can probably adapt some of their demos quite easily.

There's a reasonable chance that there's somebody at your local university that would be interested in working with some interested high school students. Finding that person could be the tricky part: I'd suggest going to the relevant department's web site and see if you can find somebody who does outreach/recruiting/admissions.
I have a couple of suggestions for Firefox...
Don't load images: Preferences -> Content and uncheck "Load images automatically".
Block other media you don't want: FlashBlock, AdBlock, QuickJava (for Java and JavaScript)
You could also try fiddling with the browser.cache.check_doc_frequency in your about:config. I haven't tried it, but setting it to 2 might yield good results.
