Speed factor relates to weapons, movement factor relates to character movement. movement is better with a high number, and has not effect on fatigue.

Speed factor, as far as I can tell, says when in the round you make you attack. As long as the target stays alive it makes little practical difference, since BG dosent simulate disrupting of physical attacks, but the real advantage comes with one-shot kills - if you can kill the target before he gets a hit in, you will never take damage. Lower numbers are better.

High numbers tend to go with high-damage weapons. Except for katans, which have the best of both worlds. And the more exotic magic weapons, anything can happen with them.
