Since I'm yet working on shaping my conventions and finding any best practises, I'll just give you my thoughts.
First off, I'll be the first to give my full support for the JSP2 way of doing things. I never really liked the "old" way, and for my projects now, I never use it. Any JSP features I use are either EL or custom tags. At times, I also use servlet filters to process the output from my JSP pages (like inserting them into a template and such). I'm not sure if that makes sense. =) So far, I've not been using the XML-syntax, and I'm mostly not concerned with language settings etc, so I felt a bit dizzy at first when reading your code below. ;) From what I can tell, it makes good sense though, even if I tend to prefer to keep the contents of the JSP pages as close to that of the actual output as possible.
