quite a few people seem to believe that wireless mice "lag" enough to warrant using a wired mouse for games. this is not always true.
if you purchase a good quality mouse you shouldn't have any issues. my old mx1000 (over 5 years old!) never had an issue to date besides running out of battery juice in the middle of something (but it has a battery meter on it)
"mouse hangups" have been known to happen even with wired mice so i wouldn't dwell to much on that.
laser mice will track (move cursor) when you lift the mouse up. optical mice wont. this means that if you lift the mouse around alot then optical mice would be better for you.
if you want your cursor to move faster then you can change the sensitivity and dpi settings to match your style. higher dpi gives you more precise control but can also cause jittering if your hands aren't perfectly still.
i would say look at logitech if you want wireless.
if you would take a wired mouse if it had a long cord, check into the razer deathadder. the cord is rather long.
