Does Canon not make a 105mm f/2 prime? Just a thought.
"L glass" refers to canon's series of lenses with an L designation in their name (16-35 f/2.8L, 24-70 f/2.8L, etc). This series encompasses lenses that are built to higher standards using better materials and optics. The special optics make these lenses very sharp with fantastic contrast and so on. Theyre also expensive, but well-worth the price to some.
A "full-frame" sensor refers to a photo sensor that is the same size as a piece of 35mm film. Most cameras (well, all but the 5D and 1Ds series, for Canon) have a sensor thats just shy of HALF that size. Larger sensor means a lower pixel density (less pixels per sq in) and an easier time with certain effects (depth of field, for instance)
