I'd guess number 1 is because you are using the wireless, and since it is a firmware upgrade, probably needs a cold re-boot.
Number 3, can you see DISTRO , that is wrong. You will need to open the Software Sources program, find those repositories, edit out the DISTRO, and replace it with Maverick. Then save, close, and reload/reopen the Update Manager.
good luck.
