If you do a google search for "free genealogy forms/charts" you will find a ton of stuff available. I make a folder for each family name and then another folder for each couple. In the couple folder I have "Individual Work Sheets" for each person and a "Family Unit Chart". (The Mid-Continent Public Library has a great Individual Work Sheet you can download). It's a big help in keeping track of what you know or don't know about a person. I put any documents/items I've found in the folders of the people they pertain to. (If they refer to multiple people - they go in the Family Name folder). I also have a folder and notebook, next to the computer, that has various Research forms in it so I can keep track of what I've searched or what I want to search in the future.
If you prefer to keep the information on your computer, I would suggest buying a genealogy program. I just bought "Family Tree Maker for Mac 2" but am only just learning all it's "bells and whistles" . (do a Google search for Genealogy Software reviews, to find the best program for your particular computer). It has a feature that allows you to add "research notes" for each person, and is a great place to put the info that your not quite ready to add to a person or to list the items you still need to research.
Good luck... I hope this helped :)
