Deploying The Personal Web Site

Rank newbie to ASP.NET here, so I'm totally "at sea" as to finding a "cookbook" for "how to deploy" a slightly customized version of the "Personal Web Site" project.

My hosting service has an ASP.NET database installed. I can verify from their "SQL Server Web Admin" package that there are 11 "aspnet_" table names present. I have run the "personal-add.sql" script which has defined two (empty) tables -- "Albums" and "Photos".

CONFUSION 1: The hosting service includes a Help fille for "Connecting to a SQL Server Database Using ASP.NET 2.0" which details the way to add 'connectionStrings' for "Personal" and "LocalSqlServer". I have made a "remote" copy of the "web.config" file and supplied the ostensively correct info for my Server, Database, User ID and Password. QUESTION: Why are there TWO names -- "Personal" and "LocalSqlServer"? Since all of the tables are contained now within the ASP.NET database are the details for both of these to be the same?

CONFUSION 2: Error handling. I'm getting "An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine." Huh!? That page then goes on to mention "<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>". I've not a clue as to what "mycustompage.htm" should contain in order to field the error[s] erupting.

POINTERS, anyone? Have I missed some basic part of the manual[s] someplace? I was sort of hoping that there would be a simple "cookbook" around someplace for how to "deploy" a relatively tested group of pages (application) in a relatively idiot-proof manner. I'm not finding it, so ANY pointers, hints, URLs will be greatly appreciated.
