On my own Windows 7 system, it suffices to leave the launcher itself open while I play the game. Alt+Tab brings me to my desktop with the open launcher window on it.

As far as the key-mapping issue goes, have you checked if "Documents -> The Lord of the Rings Online -> lotro.keymap" is currently read-only? You can right-click the file in your Windows Explorer and select "Properties". Towards the bottom of the panel there is a check-box for "Read-only", which should be disabled in order to change the file.
