In general, it refers to MIB-II, although there are times it
refers to more specific MIBs, such as the T1 MIB, etc.

At the time the original 1404 drafts were written, RMON was still
not real.  Note that in many cases we'd want more numbers (different,
or combined differently) than the basic MIBs supply (this is explained
more in 1404).

This should probably be removed in the new 1404 update (it's been 
removed in the C-S draft in favor of device).

It's the name of the thing connecting one device to another, like a
T1 between two routers that you call "boston-newyork" or something
like "ethernet 0/1", or whatever makes sense in your network.
