Answer 1

This is typically because the web part exists on a page or is in the solution gallery. Most developers do not put in feature deactivation code to clean up any instances of the web part and remove it from the web part gallery. This is why these errors come up. They need to be removed for the error to be resolved.

In a 2007 to 2010 migration, we had to go through and remove all these references because we had a lot of third party web parts that were not able to be upgraded to 2010.
