The original agreement between ICANN and the ProRegistry authorizing the extension called for the creation of third level domains rooted around a restricted number of profession specific second level categories (lawyers, accountants and doctors----ie. jones.law.pro, jones.cpa.pro, and jones.med.pro). Not long after the Registry opened its doors for business, it approached ICANN with a proposal to open the extension to second level registrations such as jones.pro and productivity.pro. ICANN granted the Registry's application. Things get fairly murky after this. That said, for your purposes, you are the registrant of a second level domain. Use of the phrase "second tier" is merely a somewhat awkward description of the same.
As to DNS services, because your registration is with Encirca, you will soon enjoy plenary DNS and related services. While Encirca's prices tend to be higher than their competition (current special excepted), their tertiary services simply out-class the competition.
Finally, please note that your registration, while otherwise proper, remains inactive. You will need to either contact Encirca or await their instructions in order to raise your account to active status. Bear in mind, however, that until such time as your account is activated, you will be unable to avail yourself of DNS and/or related services. Nor will your domain even resolve for the time being.
