I am currently attempting to use a site creator tool.  What I would like to do is expose a web service to an external application that will create a sharepoint site for every client in the external app, delete the site if the client is deleted and create a site based on a custom template if a new client is created. 

Problems I am having with this process.

 First, couldn't get sp1 for VS2005 installed, which a tutorial said was needed for my sharepoint web service to work correctly...  Error Code: 2755 occurs on the attempt to install....

Second, site creation from site templates seem to have some bugs in them.  Got a hotfix to keep webpart configuration information, however still getting a web part connection id already exists when I try to create a site from the template.  I use a query filter web part to connect to 3 custom web parts...  The client id is passed to a couple of web parts to bring back oracl information from a web service.  So the template site creation isn't working.  Currently testing in a vpc to see what the issue is...  Any input here would be appreciated.
