You might find the recent A List Apart article, Responsive Web Design, useful. It concentrates mostly on CSS, using media queries to separately target small screen devices, eg.:

<link rel="stylesheet" type="text/css"
    media="screen and (max-device-width: 480px)"
    href="shetland.css" />

You might also want to have a look at Modernizr, it won't help much with detecting a mobile browser specifically, but it does make it easy to do feature detection so you could only load an run particular scripts if certain functionality is available.

Yes, that's possible. For CSS just use media attribute for link element:

<link rel="stylesheet" href="..." media="handheld" />

For JS you'll have to detect using user agent signature whether or not visitor is using mobile device.
