Both are okay. The Projekt URL is at first used to get the scheduler URL which is read by the Core Client from a special tag in the web page found at this Project URL. Because both URL's get the same web page and the same tag this is okay.

The URL is used to identify the project in several client functions. So editing the client_state.xml is not enough and it may become a little complicated to change the URL without detach/attach the project. But as I explained above there is no need to change it.

A wrong Project URL may prevent you from getting or resending workunits and results, but has nothing to do with the credits.
The credit system with the SETI@home servers is always a good test if you are patient. ;-) I didn't believe that it is a problem of the client installation in general.
