You should be able to run it by typing its name into xterm. As for creating a "shortcut", I'm not sure how its done on different window managers (which wm do you have?), but on ICE, you just right-click, goto Create, then "New Program Icon" or something to that effect. Then you enter the path to the mplayer. It will be in one of your bin directories (there's a few of them - /usr/bin, /usr/X11R6/bin, and /usr/local/bin - off the top of my head). I think the /usr/local/bin is the default most of the time.
EDIT: Oh, and as for the start menu, in ICE there's a file in each user's ./icewm directory called "menu" where the start menu is configured. You can add it there.
