Adding AdSense

I just got finished doing some AdSense work on the blog. Instead of using Blogger's design help in the template elements I decided to go with code design at the AdSense site. This seemed to work better.

I am now running into a problem of saving and sorting all the scripts and passwords I'm accumulating. Right now I have a few encrypted Word files where I save all of my passwords, affiliate info and now HTML scripts. I can see this getting out of hand soon, so I think I may
put them in Excel and attempt to group and sort them. Does anyone have any suggestions?
