Answer 1

This should work (put it close to the top of the file):

<!-- vim: tabstop=4 shiftwidth=4 foldmethod=indent
-->

Answer 2

You're just missing the vim: modeline prefix. From :h modeline.

There are two forms of modelines. The first form:

[text]{white}{vi:|vim:|ex:}[white]{options}

The second form (compatible with some versions of Vi):

[text]{white}{vi:|vim:|ex:}[white]se[t] {options}:[text]
