LOL! Sounds like you should try FCP X! Seriously, it's ability to automatically organize zillions of clips and sections of clips by **several** different keywords is far and away one of my favorite things about the program.
Barring that, however, I would suggest making subclips and naming them well. You will also want to setup a keyboard shortcut (there doesn't seem to be one by default). The menu item is under the "clip" menu. I know it seems like a lot of work but, with a keyboard shortcut set up, all you'd have to do is mark in and out points, hit the shortcut, a dialog box will popup prompting you for a name, and you're good to go for the next clip. Then make bins for each type of clip so you'd end up with a bin full clips names "montage_01", "montage_02" and so on.
I have found that taking the time, upfront, to organize your media **especially** if you have an awful lot of it, really saves a ton of time in the long run. Best of all, when the deadline is looming and you need to find a specific clip, it's right there where you put it.
