Subdivide = Smoothing in Wings 3D. (It's Catmull-Clarke subdivision to be exact.) Loop cut = A mesh editing function in wings. Select any series of edges that are end to end such that they form a closed loop. Then by loop cutting, the parts on each side of the edge loop become separate meshes. Greeble = Any pipes, clutter, doo-dads, etc. added to the surface of Sci-fi models for the purpose of depicting size and added detail. If you've seen any StarWars movies, you've definitely seen greebles. It's just a term that some hollywood F/X guy coined.
