As you stated, other than the financial management course certificate there are no other filings necessary unless requested by the court or trustee.
Other than the FMC and accompanying declaration, the court does not require further filings (assuming that your creditors' meeting was concluded). However, you may need to sign and have filed a reaffirmation agreement if you are reaffirming a car loan or other secured loan. You will probably need to discuss the pros and cons of signing a reaffirmation agreement with a bankruptcy attorney if you have any secured loans and want to keep the collateral.
As other have stated, you will just need to complete the Debtor Education course and file it with the court.
Just a quick note - be sure to look out for your Discharge notice because sometimes the courts get backed up and do not discharge you. If this happens, just give them a call and they will be more than happy to take care of it.
Good luck to you!
