Well done on inheriting such a treasure trove. Now as you have realized, you have a mammoth task in front of you.
As others have already said, you need to make a catalogue or inventory of everything. To save time, perhaps get the acid-free sleeves and boxes mentioned by Mike, and as you catalogue things, you can sort them as well as putting them into protective sleeves etc. that will save them from any further damage/deterioration. Perhaps ring binders might be a better way of sorting things into some sort of order. How you divide things up is entirely up to you; you are the one that will be accessing the collection.
Good luck in this huge undertaking.
