Corrections:

>  - m .|. is modifier of keys 
m is a modifier bitmask -- 0 means nothing pressed, shiftMask means
shift pressed. m .|. n is the combination of two modmasks -- in this
case m .|. mod4Mask means "mod4 and m held down". Here, mod4 corresponds
to W.greedyView, mod4-shift corresponds to W.shift.

Yes. See:
  ~$ ghci

  Prelude> import XMonad

  xK_KP_1 :: KeySym   -- Defined in Graphics.X11.Types
If you search the internets, you'll find documentation for the Types
module, including a list of all the KeySyms. (Assuming it's up to date.)

windows is a bit of a magical function. It converts a pure StackSet
mutator into an X action. In other words, f is all the business logic
that says "move this window here" and so on, and windows is the dirty
greasy implementation that actually interacts with X.

In this case, f is either W.greedyView or W.shift. See StackSet
documentation or source code for info.

i is the window number extracted from xlib. See `xprop`, for example.
