What you can do is structure your Javascript to work with those browsers
that utilise standard DOMs.

To enhance the user experience.  The server side validation is there to
catch users without Javascript and those who may try and do things they
shouldn't.

No, the interface is (hopefully) simpler to use for those with
Javascript.  There may be some extra work in creating the Javascript to
do the validation.

What do you mean by this?  In my experience it seems to becoming more
consolidated.  Firefox has basically pushed MS to release a standalone
version of IE that fixes many of the issues plaguing web developers
using standards.
