You overlook other creditors who would need to be paid - the Trustee and other professionals. You made the choice to file a Ch.7 and there is no "do over" after the Trustee finds assets and starts to liquidate. This was something to discuss with your lawyer before filing.
You probably ought to get an attorney to represent you as filing Chapter 7 under these circumstances will be costing you a bundle, not to mention the aggravation. Properly structured, a Chapter 13 could allow you to make payments to satisfy your IRS debt at 0% interest with no more penalties, retain all the nonexempt property without it being liquidated, and allow a discharge of your other debts. There is a reason why people pay bankruptcy attorneys a substantial fee for a Chapter 13 - because it can save you a lot. Hope you don't end up learning the hard way that without a license to practice law & years of experience, you are not qualified to plan for bankruptcy on your own.
The IRS is a priorty creditor, so they will get paid first. Other unsecured creditors' amounts will be discharged.
