I feel you might want to consider having one room full of boards as a "donor" in order to repair the other rooms..... sure you can match new boards to the rest but this is a big job I believe as you would first need to get the same species, then the same general look, then machine/sand/plane them to the same thickness as their counterparts, then colour-match and laquer - then fix to the bearers...... also, removing the existing "damaged" boards may result in at least slight damage to the existing boards depending how it is done.....one thing you will probably have to do with any replacement boards is remove the lower side of the groove so you can get the board in place..... which lowers the strength.....
fun huh?
Hope this is at least a little info if not very helpful.
