Well, I've been doing quite a bit of programming lately, however, it has been in a number of different languages. Naturally, I have considered Eclipse as a possible editor. Vanilla Eclipse is usually geared to toward Java development and can become tricky and tedious to setup for Web Development (hence the rise of Aptana). Eclipse can be great to work with, but only when you can get it working how you'd like. The following update sites may be helpful to get Eclipse setup how you hope to have it:
JavaScript
http://download.macromedia.com/pub/labs/jseclipse/autoinstall (JSEclipse)
Python
http://pydev.sourceforge.net/updates/ (PyDev)
PHP
http://update.phpeclipse.net/update/nightly (PHPEclipse)
Java Tapestry
http://m2eclipse.sonatype.org/update (Maven2)
http://jettylauncher.sourceforge.net/updates (Jetty)
Currently, all of these plugins can be loaded into a single installation of Eclipse Europa. However, I'm not sure that they are all compatible with Ganymede (latest version of Eclipse).
