About That Mouse Disappearing After Sleep... A Thought...
Although it may sound strange, some of those problems have been fixed by installing the latest Broadcom WIRELESS driver.. IF you have the Broadcom device on your machine, check to see the driver version and date. You may have an older one that the link below. (It has something to do with the wireless device holding things up as it attempts to connect after the sleep mode.) No guarantees, but see the link below for the most recent driver.:

Hope this helps.
