CHIBISKUNK'S PROFILE

I am using RMXP and I am trying to make the first scene which is using the Farm Village in tile set, a couple questions, first is there a graphic for an open door, if so how would I set up a trigger so that when a character walks into a closed door it becomes an opened door?

I just downloaded the maker today and am trying to work on a game, I have checked the help section and browsed a few of the resource pages without figuring out a simple thing, how do I move the main character starting point on a map?
