Just override the variables:

    (dolist (map '(evil-normal-state-map
                   evil-emacs-state-map
                   evil-visual-state-map
                   evil-insert-state-map))
      (set map (make-sparse-keymap)))

There are some maps missing, (apropos "evil.*state-map") will show them
to you.
Just add those to the list if you want to reset all.

No. The former defines a mapping in an additional keymap for the normal
state when `global-map' is active.
The latter defines a mapping in the normal state map.

This is not only a technical detail but has also consequences on the
priority of the mapping (i.e. which definition would shadow).

For (evil-)global mappings the latter is preferable, for mode local,
e.g. for org-mode, the former is the way to go.
