Yeah those are all very good resources! For my town, one of our players made a custom spreadsheet for the gamecube game specifically without all the fluff information. Just sheets separated by furniture, museum items etc. and then sub categorized by the series and a percentage completion for each individual playing. That way we can all coordinate if we need a single piece in a series that someone has gotten at some point in time. I can make a copy and share that with you if you like!
