I assume this is for white list filtering? If so yes, then for question 1, just set a DHCP reservation for that MAC. As part of that you can set a name. Second, a computer with a static IP is not going to show up in the LAN list, because that list is only the IP's given out by the router's DHCP range. You can still see what is connecting wireless by clicking "wireless sessions" or see everything that has active data connections by clicking on "Internet Sessions".
