Procedure to get Partnership Firm Registered

Hi, I have registered my firm online with Registrar of Firms Website through Form A (The business shall be one in Agricultural products and I have given my home address for the same). I have a couple of questions being: Whether Do I need to apply for Gumasta License if I am going to do the business from my Residence (there are two partners)? After the Form was submitted successfully I have received a documents check list to be submitted in physical form which includes (I) Certified True Copy of the Partnership Deed; (II) blank stamp paper of Rs. 10/-; (III) Authority Letter signed by Partners if the documents are submitted by a CA or an Advocate (is this still to be submitted if I am personally submitting the documents: this was showing as mandatory); (IV) Covering Letter- can you please explain what this is? Also kindly let me know if I am supposed to take any other steps or follow some other procedure to go ahead in this matter? Thank you in advance
