I would recommend a different lens. The 50 1.7 is more like 75mm on a crop frame which makes it a great telephoto lens for portraits and not much else. It will be rather limiting for landscape/street photography and also for large indoor scenes (thought I admit the F1.7 is nice). What I would recommend is you either start with the kit lens and as you improve move onto different focal length primes or start with a nice zoom like say tamron 17-50 F2.8 which has both wide angle and portrait capibility and is considerable step above the kit.
On a side note, if you really want the 1.7 you can get a A 50mm 1.7 on ebay for like $50-60 as well, and just sacrifice the auto focus
