I've also been working on some design issues related to Pier, including
removing the use of tables. I ultimately decided to start with a minimal
existing css framework (scribbish), and modify both Pier and scribbish
into something useful. I wrote up a tutorial about the process:

Links to download the image/changes file and the css files are at the end.
I learned quite a bit in doing this, but I still have a quite a ways to
go. I hope it makes sense. Enjoy!
