Definitely the 50mm f1.4 - it approximates the human eye's angle of view, and is the most versatile focal length: move in for a nice shallow dof, or step back for reasonably wide shots.
I wouldn't get hung up on what 50mm 'means', but generally think of lens focal lengths in three categories:
wide angles (35mm or less in focal length)
telephoto (85mm +)
eventually you'll want one of each. I'd probably look for a good 35mm or 28mm focal length next. FDs are so inexpensive you can get fast lenses for not much $$ at all.
Also consider Canon FL lenses, the precursor to FD lenses, which are also excellent buys.
PS - in case you absolutely have to know: the focal length of a lens is defined as the distance in mm from the optical center of the lens to the focal point http://www.dpreview.com/learn/?/key=focal_length
