F-reorg: Balance Sheets and Taxes Post-Acquisition

We acquired a healthcare company that was a S-corporation and did a "F-reorganization" + conversion to LLC. Above that LLC, we have a few holding companies where equity and debt capital came in (two different entities with different EIN numbers). A few questions: a) do you create separate balance sheets for each LLC - holdcos and opcos? b) for tax at year end, do you consolidate all financials and balance sheets at year end or need to file separately? c) does the closing balance sheet (pre-sale) go to zero or does the new entity retain those assets and liabilities? There was old goodwill for instance and typically we reset that to zero but wasn't sure what happens in a F-reorg.

Welcome any thoughts or advice.
