I loved ACDSee when I was in Windows. I would definitely start using it. I think Jessica Sprague offers a class in how to use ACDSee?
ACDSee lets you assign categories to files. You choose which categories you want to use, and that depends on how you like to organize. I organized papers in different colors, and by type (floral papers, graphic papers, solids, and so on). I had a "preview" category, and categories for different types of embellishments. You can find a lot of info here:
Welcome to DigiScrapInfo!. They are dedicated to digital scrapbooking, and to organizing with ACDSee. They have a few suggestions on how to choose categories, and you can download them too.

I have never used Bridge, so I don't know how it's different from that...
