I have a 28-70mm and a 70-300mm. I would love the 50mm as well. One thing to note, if you are going with a larger zoom lens, make sure it has Image Stabalization. My 70-300mm does not have IS and I have only pulled it out of my bag a total of 10 times in the 3 years/9200 pictures that I have taken. You have to use a tripod to get a clear picture unless you have a REALLY steady hand. I am also looking for a larger/wide angle lens. Maybe for Christmas ... a girl can dream!
