Actually we have to take an appointment either in Passport Seva Kendra (PSK) coming under the RPO (He can log on to psk website and there he will get directed to select the psk according to his RPO) or directly to the RPO. Anyway all the application will go to RPO for issuing PCC or passport or anything related. They will either send you the PCC by registered post or will tell to collect it from the office directly. But before doing anything kindly go through the psk website instructions for applying for PCC. 

Hi! As per my knowledge, your husband need not to add his spouse name in his passport, if he is applying for a spouse visa (CR1). But if it's a dependent visa then he should add the spouse name. For applying for a passport he can show the adhaar card or a bank account book with the current address on it. In this case, he doesn't need to submit a rent agreement.
