If I opt in for the Trademark Claims service, will I be notified if a domain name applicant requests a domain name for my trademark registered with the Clearinghouse? Or will I only be notified when this domain name has registered my trademark?

You will receive a Trademark Claims notification as of the registration of a domain name matching your trademark record, not one that is similar. You will not receive a notification if the domain name applicant decides not to pursue his/her request to register a domain name matching your trademark record after he/she has received a notification informing him/her of the existence of your Clearinghouse trademark record.
