I am sure there are posts out there (I found Geoff’s one here) but just in case I wanted to write a quick post highlighting two important aspects about SharePoint WebParts, and the WebPart Gallery (for SharePoint 2007 AND 2010).
- You can hide certain webparts from certain users/stop them from being able to add these webparts.
- You can modify webparts in your webpart gallery so that they have better descriptions or adjusted names.

Hope this helps,
