@Stephen, I have never tried PDF's through google docs. I just usually find the spreadsheet versions so it makes calculations for people. Like this one for pathfinder I just found (typed in google docs "x game" character sheet.)

Yes, in Google Docs, you can create folders and folder in folders, then you just drag and drop the sheet into whatever folder you want.
