Not much. Most documentation is linked from the website
<
http://www.piercms.com/>. Also some people (including myself) wrote
blog posts on extending Pier.

This is a code repository, there are many other extensions if you
search on www.squeaksource.com.

Any Seaside component is a Pier component and can be directly plugged
into a Pier site. However, if you want your Seaside component be able
to interact and reflect on Pier it needs to know about Pier, for
example by subclassing PRWidget which is a subclass of WAComponent
with some added functionality. This is the only difference.

Not necessarily, but it will make your life much simpler.
