Yes, cocoon is wonderful and powerful! There are a lot of companies 
using it now.

Place this lines before mounting, this should do the work:

<!-- Redirect to the user directory if the ending slash is missing -->
        <map:match pattern="~*">
            <map:redirect-to uri="{0}/"/>
        </map:match>

IMHO, the question is too extend to being answered in a mail. There is a 
nice introductory block called "tour". Run cocoon and see the samples. 
If you want to concentrate on cforms, I believe this links can help:

Presentations from GetTogether event presentations you can speed up 
cocoon learning: Go to cocoon download area: 
http://cocoon.apache.org/mirror.cgi click on "Material from events" and 
there see this presentations:

from gt2003 (all of them have also videos of the presentation. Download 
the video and the PDf to follow the presentation):

11-visual-journey.pdf --> A brief overview
13-woody-flowscript.pdf --> How to use cforms with flowscript. Keep in 
mind that woody is now cforms.
16-lightweight-tool-presentation.pdf --> CVS is now SVN but not 
important from the presentation POV. Here you will learn about the toold 
we use in the community.

gt2004 (unfortunately no videos. Will be fine to add the videos no 
matter it is from the last year) - [Did you hear me Jeremy? ;-) ]:

JeremyQuinn-GT2004.pdf --> About how to avoid mistakes. Partially answer 
your question. ;-) It is good!
gt2004-bertrand (part I and II) --> explains how works cforms in a Db app.

Other interesting links:

http://cocoon.apache.org/2.1/userdocs/forms/index.html
http://wiki.apache.org/cocoon/CFormsMinimalExamples
http://wiki.apache.org/cocoon/WoodyHelloWorld   <---- Take care to 
change the namespaces to adapt to cforms

I hope this help.
