There is no such thing as the refresh rate for a mouse. Also you can not overclock your mouse. There is sampling rate and resolution. Think of a sound card. A higher or the faster the sampling rate gives you near the same quality of the sound. The resolution is how many steps of points to take of the signal for each sample. The sampling rate is measured in milliseconds (I think) and the resolution is measured in dots per inch or pixels per inch.
To set these values you need to add or edit a line in XF86Config. Its usually under /etc/X11. In that file find the Pointer section and add/edit SampleRate and Resolution. Read your maximum mouse settings before changing the sampling rate and resolution.
Code:
Section "Pointer"
SampleRate nnn
Resolution nnn
EndSection
nnn = a desire number that you want to use
Wireless will have a lot of latency problems. You may want to use a wired PS/2 device because there is not much conversion circuitry.
