Imagine I have bundle A 1.0 that contains some initial content
definition for my webapp. The development goes on and some more
content is added or maybe even some resources are removed from the
bundle. The new bundle is deployed as A 2.0 to Sling. How is the
update process handled?

1) Are new resources added to the JCR?
2) Are existing resources overwritten?
3) Are resources removed that are in the JCR but not in the bundle? (I
can not imagine how that should work but maybe Sling has a strategy
for that).

it depends on your configuration, please see options "overwrite" and 
"uninstall" on page http://sling.apache.org/site/content-loading.html
If you uninstall a "path", even content not in your bundle is removed from the 
JCR - so be very careful.

O.
