Answer 1

There are a few problems with the config above.
The service element has the name attibute which is not fully qualified name.
The endpoint element has the contract attribute value which is not fully qualified name.
A fully qualified name is as shown below:
MyWCFService.TestService (i.e. namespace.ServiceName)
If you are running the same on Cassini web server then right click on properties and under the web tab make sure that the "User Visual Studio Development Server" option is selected and the "Auto-assign Port" option is not selected. Rather select "Specific Port" and use 8001 to match your configuration

Answer 2

The <baseAddresses> configuration is only for self-hosted services + applications, and is not used by IIS / WAS.
Where you 'put' the .svc on your web server / site defines its url, unless you are using a feature such as file-less activation (article here)
Your IIS url will be something like
http://localhost:8001/MyApp/TestService.svc?wsdl
I'm not sure why WCF test client is defaulting to the wrong URL - just type in the correct one and it will cache it.
