Based on LG's PR in January 2007, it seems only the LY series models will feature 120 Hz TruMotion, as well as 92% wide color gamut.
I don't believe LB has any meaning other than as a model designation -- L could signify L in LG or L in LCD. LG has LC, LB, and LY lines of LCDs.
LG hasn't announced anywhere that they are using LED backlighting.
