easier to define it as
Position[] pathToBank = new Position[]{new Position(0,0,0), new Position(0,0,0), new Position(0,0,0)};
etc.
Also, in terms of the walking, try and space the points 2-3 tiles away from eachother to ensure they dont get stuck. I've converted a tool which records paths for you (found here: http://osbot.org/forum/topic/61609-path-generator-zwalker-portre-release/ )
