Assuming those are buildings set down by blizzard, they are 'doodad's not gobs, so you can use the '.doodad near' and '.doodad select' commands to inspect them and see what they are in the chat.
If you want to modify the specific wmo, I think you have to phase shift them ('.phase shift doodads adt' or 'phase shift doodads zone') and then use '.doodad mass import' to hide the doodads and then turn them into game objects for you to move etc.
Also be aware, that sometimes wmo's are a bit big or unwieldy, found that out when I tried to use parts of silvermoon, only to find out, that silvermoon is one giant wmo.
