You really should be talking to Real Estate Agent about these issues, along with your Loan, Title, and Escrow officers. They should be providing you with all the neccessary paperwork and information. YoOu can always check your county's assesor's page to check the record for the property and see who's name is on the record. IF it is your name, then you have been recorded as the owner, and should have the keys.
If none of these "professionals" provide you with adequate information, it would be time to talk to a Lawyer, specifically one who has a real estate background.
