I found the FAQ on JavaRanch about setting CLASSPATH to TOMCAT_INSTALL_DIRECTORY/common/lib/servlet-api.jar, which in my case is ...
- I still get the same compiler error - even after rebooting

Somewhere on this site there is a nice description of how to install JDK and the PATH and CLASSPATH. path and classpath are for different purposes. path is for the OS to find commands, classpath is for the jvm to find classes. Your classpath looks reasonable.
Remove c:\Program Files\Apache Software Foundation\Tomcat 5.5\common\lib\servlet-api.jar from the PATH, it doesn't belong there.
Also, remove c:\Program Files\Java\jdk1.5.0_07\bin; from the CLASSPATH.
PATH and CLASSPATH are two different things. PATH is used by the operating system to find executable files. CLASSPATH is for Java only, and is used to find Java classes. To see what either of those environment variables is set to, type:
