Organizing with iPhoto

After reading various books and articles, and experimenting, I've finally come up with a routine/strategy for organizing and archiving my photos.

Import images and video clips (if any) via Image Capture.
Group related images into folders, either during or after importing.
Open iPhoto.
Drag folders one by one into the album pane.
Each folder then gets imported as an album and as a film roll with the folder name you entered.
Set the title of each film roll to blank or the roll info title.
Make backups of the Photo Library to CD-RW or DVD-RW depending on the size of the Photo Library.
When the Photo Library size will fit almost all of a disc, make a backup to CD or DVD (not RW).
Rename (safer) or delete (more risky) the iPhoto Library folder and create a new empty one.

Optional:
Make a disc image of the CD or DVD using Disk Copy to mount the Library without having to use the actual disc. It's easier than switching between Photo Libraries.
