G = no aperture ring
ED = contains at least one element of extra low dispersion glass
D= the lens passes the focus distance to the camera
IF-= internal focussing, the front element stays still during focus (but may rotate during zoom)
VR is indeed vibration reduction.

Lists like these is one of the few things where you can trust Ken R.

AF-S: built in wave motor enabling autofocus with entry-level Nikon DSLRs.

DX: lens is designed for the DX format, meaning its not fully compatible with 'pro' bodies such as the Nikon D700 and D3.

Nikkor: this is the brand of the lens.

35mm: this is the focal length of the lens. Used on a DX camera, it will translate to a 50mm lens in full-frame terms.

f/1.8: This is the f/stop. The smaller the number, the larger the aperture, and the more sensitive it is to light.

G: guilded, meaning it lacks an aperture ring. This is usually not important to most people unless you happen to be using an old manual-focus film camera.

VR: vibration reduction. Useful in low light when you don't have a tripod with you.
