fender removal

I feel kinda dumb for asking this , but why struggle to figure it out when I'm sure other ppl have done this.
And the manual I have doesn't say crap about how to go about it & the other manual is lost.
I'm not sure exactly where all the points are for removal of the front fenders ?
It looks like to remove the one bolt that is near the front pillar , kind of inside the fender , I would need to remove the door to access it ??
I'm getting ready for paint & the fenders have some rust at the bottom & I'd like to take them off & repair them the right way.
Also , how much of the front end is part of the fender ? I've done a lot to cars , but never had the fender off.

ANY tips , advice etc......thanks a million !
