the ideas here are nice...
if i had to do that here are some things i would do:

organise all our old and new photos - online order prints of those i dont have and get heaps of albums and arrange them all nicely (also maybe could do photobooks instead - all can be done online)
organise all my recipes - not books but i have heaps of magazines like delicious, donna hay etc so i could tear out recipes i like and organise them into a book/box/folder and then throw out the mags i dont need
print out emails from our travel - i used to write long and lovelty email home with all we got up to - and make memory books of them (in fact i think i will try to do that now). i would prob create a memory book from some of the trips for DH, i am sure he would love them
write letters to some of my relos overseas - email is good but some of the older ones would love a handwritten letter - and add some pics of our kids etc
i'd also be doing all the thank you cards for presents for Jacob, but i guess that's a bit premature for you to do LOL
hope that helps and hope the time goes fast!
