Two technical questions about Quake 4

[Starshot]

Hey everybody,

I got two questions regarding Quake 4:

1. Is there a way to permenatly save the "pm_speed command" to the configfile (or anywhere else) so I don't have to put it in manually everytime I die?

2. Is there a way to fixate the weapon so that it won't move around when I stand still or walk?
