Can someone with access to TDN help me with some infos?

I am on demo so kinda in rush to get these things figured out since limited time to determine if we will keep this program or not. Im trying to get more info, examples, tutorials on the TileSets/Layers things, as well as the scripting refrence its self. The scripting refrence is most needed, would like to know what does what and how to use them since the included examples dont have all the commands im sure. As for the TileSet part, I can make them just have no clue how to use them with thier collisions in the game if would seem. I am attempting to make a PacMan clone, made the level in TileMap, put a sprite as the player and the TileSet on COllisions, but wont stop the player from moving over top of them so not sure how to access that collision info in the scripts on the player.
