Answer 1

Looking at the documentation you can see docs for where they spell out the classes to what you need to update for styling.

http://visjs.org/docs/timeline/#Editing_Items

Also they have events for onmoving and such so you should be able to drag and animate built in but I couldn't find a clear example of it in their docs.
