I use the 18-55 kit lens for 90% of my shooting, and it hasn't failed me yet. It is a good size, has a reasonably small aperture, and the build quality is very premium. If you were to invest in another lens, however, get the 18-135. It is an amazing all-purpose lens, and when I had it, I never took it off the camera.
Don't get me wrong; the 18-55 is a great standard zoom lens. The only thing is that, typically, for most "consumer" DSLRs, the 18-55 lens is a quick (and cheap) way for manufacturers to get the consumer drooling. Of course it's a good lens. It's simply not the best. Whether or not you decide to keep it is your choice as the 18-55 can be a useful tool for general purposes.
As far as 18-135mm lenses go, from what I've heard they are superb. I have read reviews on some lenses, however, where there is some noticeable chromatic aberration when zoomed in fully and the aperture is wide-open; but this should be expected with most far-length zooms.

I've owned the Sony NEX-5 and Sony a55. Both cameras were not supported in StopMotion Pro and Dragonframe, and I don't think they will work with other third-party animation software. Unfortunately I think the only way to have tethered shooting with Sony DSLRs is to purchase a USB-to-video cable for about $45. There do not seem to be many Sony users in the stop-motion community, but I'm sure you'll find a way soon.
