I currently have the a-200k kit, and lenses are really based on shooting style and preference.
The lense it comes with is a Macro lense, and what i currently need/want is a zoom lense, so yes, i would stay with the 200mm zoom.
Where do you live? i would try to find a local camera shop or within a 30 minute drive.
other then that, try ritzcamera.com (i think that's the site, just google ritz camera if it isn't)
