The info on that page is just an example. I didn't mean for you to do
just do what it says there w/o thinking about it :-)

I suspect that /usr/bin is already in your exec-path. To find out, type:
ctrl-h v

You should see "Describe variable" in your minibuffer, where you would
type "exec-path" (no quotes). A buffer will open showing you the
contents of this variable -- I think you'll find /usr/bin there.

No.
