You will have to get only one PCC from your regional passport office.
Plz find the details for the same here.http://passport.gov.in/pms/Police%20Clearance%20Certificate.htm
You need to give the address proof and they dont accept rent agreement for that.
You can give your bank account statement for the account which has your current address.
Also it is mentioned on the website that
A set of three completed Personal Particulars Form if the applicant has not stayed at the present address for the last one year
But they ask for it anyways so better be prepared and also carry 6-7 recent passport size photographs.
