M-x apropos point

Command `apropos' is your friend.

The Elisp manual, not the Emacs manual, is the reference for Emacs-Lisp
code. All of the functions you have asked about are explained there. Both
manuals are available via `C-h i'.

Correct. Actually, both are discouraged if the user doesn't expect any
change. To move point temporarily to obtain a location, wrap the movement in
`save-excursion'.

Again, this is explained in the Elisp manual.

(point-min), not 1.
