The source-bridge transparent command is only needed if you are bridging between the token-ring and ethernet on the same router. It is not needed if you are using dlsw to peer between, for instance, R1 token and R2 ether AND R1 ether and R3 ether/token.
The virtual ring is not required on the EN router. Some configs had this on CCO but it doesn't do anything. If there is no token-ring interface on the router, a virtual ring is not needed, but the dlsw bridge-group is.
