Answer 1

If you choose the Recipient type is "E-Mail address", you can enter the email of the person manually to whom the email should be sent or you can still choose an expression (Container) which will have the value determined dynamically.
If you choose the Workflow Initiator, the notification goes automatically to the user who has started the workflow.
If User, you can enter the sap user id manually or determine dynamically using expression.
If expression, you can choose a container element which holds run time value.
Regarding the binding errors, you can generate the binding automatically.
