Bluetooth and 802.11b/g both use 2.4GHz. They're going to step on each others toes every so often. Some wireless chips will have options to be more accomodating regarding Bluetooth but at the end of the day you'll still get odd problems every so often.

See above. If it is bad enough that the mouse loses the connection totally then it'll take a few seconds to reconnect.

Plug the receiver into a USB extension cable and put it closer to where you mouse is.

You get it for non Bluetooth ones as well.
