Some useful resources include the following:

www.gamedev.net - if you click on the "for beginners" link on the left side of the page, you'll find a lot of information useful for new game developers.  This site is an excellent resource for game developers in general and its forums are geared towards beginners.

www.devmaster.net/engines is also a useful source of information.  You can search the data bases to view game engines by programming language or by feature.  

The most complete list that I've come across is at www.ambrosine.com/resource.html.  It lists a number of game engines with a brief description and links.  They also list a few of the more popular sound and graphics applications.

If you're looking to start developing your own game, I'd also highly recommend lurking on the indiegamer forums.  You'll run across a wealth of useful information from some of the most successful indie game developers.
