Wow, two Fortran questions in g.e.h in one day!

I don't know what you mean with respect to the indentation appearing
"automatically". Pressing the tab key on a line of code will indent
it. F90 mode has the command `f90-indent-subprogram', on C-M-q, which
will indent the whole of the current subprogram.
`f90-indent-new-line', C-j, will indent the current line and start a
new, indented line.

To have keywords be capitalized automatically in f90-mode, add the
following to your .emacs file:

(setq f90-auto-keyword-case 'capitalize-word)

Or you can use the customize interface (see below) to achieve the
same result.

The commentary section at the start of the file f90.el describes some
of the possibilities. I'm afraid there is no section about F90 mode in
the Emacs manual (I started writing one a while ago but haven't
finished it). You could use M-x customize-group f90 to see what
choices are available.

The luxury of choice (or something...)

There are various ways to enable mouse wheel support. Try:

(require 'mwheel)
(mwheel-install)

in your .emacs.
