Answer 1

You can get caught on a rubord branch.
You can go to marklets.com
You can google, finally - it will give links to the main collections of bookmarklets.
But a good collection will take a long time to collect. I have a bookmarks file that contains a bunch of bookmarklets, but no descriptions (although they are sorted into "talking" folders). True, a lot of things there are already outdated (many bookmarklets are tied to web services and are gradually dying out)
