well best thing is to go through the tutorials on this site, 2 or 3 i think
see about moving a sprite around, once thats done
a) design up all your sprites/tiles
b) place your tiles into the name table
c) get your character onto screen, calculate how much distance you need to move character each movement, change the tiles for the sprite each movement
d) do the same for any other things that move on screen
e) do collision detection (not important until you get to this stage)
