At CommunityOne, the Sun GlassFish Web Stack team gave a "Deep Dive" series of presentations on the web stack. Sun GlassFish Web Stack includes a fully integrated Apache, PHP, and MySQL package, as well as the GlassFish and Tomcat servers and Python and Ruby support (and lots of other stuff, too). It's currently available for OpenSolaris and Linux RedHat. (Note that if you don't want OpenSolaris as an OS on your machine, the stack works very nicely on OpenSolaris in a Sun Virtual Box VM.)
The team's presentations are available as videos from Sun Learning Services. If you don't mind getting a My Sun Online account (or you already have one), you may find these presentations interesting.
Probably the two most broadly relevant presentations are:
