The more expensive "pro" 50mm lenses; usually the f/1.4 or f/1.2 were the mainstay for existing light film photograhy, because of the relatively low ISO values of film, versus what a modern DSLR can do. I find 50mm lenses are a bit limited for crop frame cameras.
With your crop frame (1.6 crop factor) Canon, this lens is a short telephoto lens and is getting into the range of being a pretty reasonable portrait lens; although I prefer one that is a bit longer. I'm not sure how useful you will find it as a general purpose lens; somewhere around 30mm would be better with your camera, I think.
I am a fan of prime lenses (I own four), as they force you, especially as a beginner, to move around to compose, rather than picking up the bad habit of standing in one place and adjusting the focal length on your zoom. This means you will develop a better skill set as you improve. Even now, when I find I'm not happy with my composition, I will pop a prime on my camera and go out and shoot with it, just to re-enforce my composition skills.
