You can order a NetBeans Starter Kit DVD directly from the netbeans.org (here) website, the DVD will be sent to You for free (all shipment costs covered by Sun). The idea is similar to Ubuntu and OpenSolaris shipping option. My copy of the DVD arrived today while I was at work. This is a very nice option for people with limited or slow bandwidth. It's also nice if You don't like to Google for reading materials.
The Starter Kit DVD contains software distribution files for Windows, Linux, Solaris x86, Solaris SPARC, Mac OS X and the following list of items
I stumbled upon a nice tour of DrScheme, showing most of it's nice features. The only thing irritating in the video is the volume. Be sure to turn Your speakers up.
Scheme is dialect of Lisp and is one of the many languages supporting the functional programming paradigm (although it supports other paradigms as well).
There is a great text-book called Structure and Interpretation of Computer Programs available for free online. You can find it here. The text-book doesn't focus on the language itself but also on many aspect of computer programming. You will find the topics covered by it useful even if You decide not to code in Scheme. There are also video lectures (available online and for download) that are a complete presentation of the course, given in July 1986 for Hewlett-Packard employees. You can get the videos here or alternatively You can find them on Google videos by entering the search term SICP. I encourage You to schedule some time and at least go through lecture-1a and lecture-1b. That should be enough to get You hooked
