Answer 1

There is no point in WSDL for REST services created with WCF because WCF supports only WSDL 1.1 (or 1.0) which cannot describe REST seevice. If you try to use WSDL generated for WCF REST service to create a client proxy you will not be able to call the service anyway. Visual studio templates for REST don't expose metadata so you will get useless WSDL only if you add serviceMetada behavior (and possibly also mex endpoint) yourselves.

WSDL 2.0 and WADL supports description of REST services and the point is similar as with SOAP services - describe what you can do with the service but in the REST way.
