Lots, especially performance.  There are some configuration differences
between the two, so read the docs carefully.  Consult the changelog and
FAQ for details.

I'd go with 5.5 - the newer level gets more attention from the
developers and has definite performance advantages.

No, just download what you need.  Look here:

I posted a more detailed description of the download packages a few days
ago.  Try:

The key issue is "primarily" vs. "only".  If you develop with 1.5 you
run the risk of not being able to execute on a 1.4 system if you have
written code that depends on 1.5 features.  You only need the
compatibility package for Tomcat installations that are actually running
on 1.4.

Tomcat is built with 1.4, but runs happily on either 1.4 or 1.5.

Got me.  I'm a command line person.
