I think PunkClown and Rork did a pretty good job of answering your questions. Your 28-200 is a pretty good overall lens. 28mm is considered wide angle.....and 200 mm is telephoto. My suggestion would be to learn and get as good as you can with that lens before you consider spending lots of dough on a lens you might not use all that much. Besides you may want to say that money to buy a better quality 28-200mm.... (not saying your's isn't good, you didn't say which lens it actually is).

I am, therefore I create.......
