| How do I make the mouse wheel scroll a given number of rows at a
| time. Is it even possible to configure # pixels to scroll?

You may customize the variable mwheel-scroll-amount.  I'd be
surprised if you can scroll by pixels, though.

I found this by doing C-h k <scroll down>, which told me which
function was bound to <mouse-5>.  The Help buffer shows

    <mouse-5> (translated from <down-mouse-5> <mouse-5>) at that spot
       runs the command mwheel-scroll which is an interactive compiled
       Lisp function in `mwheel'.  It is bound to <C-mouse-4>,
       <S-mouse-4>, <mouse-4>, <C-mouse-5>, <S-mouse-5>, <mouse-5>.
       (mwheel-scroll EVENT)

    Scroll up or down according to the EVENT.
    This should only be bound to mouse buttons 4 and 5.

    [back]

Middle-clicking the underlined `mwheel' took me straight to that
function's definition.

Another way to find this is doing C-h a wheel, which gives similar
pointers.  

Take some time to learn the Emacs help system and documentation; it
is quite good.
