1) Let users create or submit but set articles default to unpublished.
2) We have a free notification plugin for the webmaster.
3) Webmaster has publishing rights and can check and publish items either via front or back-end.
In F2C Pro you have more control and can hide many fields to make submission easier. You can also make a menu link to a single article submission form.
Hope this helps.
Please read the F2C documentation before asking questions! Thank you if you've done so
