When i have the bone animations imported, do i have to attach all of the verticies to the different bones, or what?
That depends if you import the entire boneskelet with the animations. Or that you only import the animations, for example using the import keyframes function. Anyway you will have a hard time finding somebody who will give you a bone animation. Because animations are hard to make and take a lot of effort. Therefore people don't want to give them for free.
