With VLC you can control playback speed via the 1.00x part of GUI. (or via
rc interface, or via --rate= command-line parameter)

Depends about what you want. Usually if you just make playback faster, you
don't need high FPS, but if you want to slow down stuff and keep smooth
motion, then you will benefit from hight FPS.
