I believe on the main D&D site there is a good character creator tracker thing thats free to use for low level characters. It I believe is pretty slick and allows you to print out nice like cheat sheet things that have all your powers and what you need to roll already pre calculated which makes figuring out how to do things fast and easy.http://www.wizards.com/default.asp?x=dnd/insider/characterbuilder
As for maps in the back of the DM book there are some template dungeon floor maps just find hex squares similar to that if you want bigger maps. Any gaming store will typically have grid paper of this size for sale pretty cheap.
This looks like a pretty decent lil quicky map maker that you can print stuff out with.http://yeoldemapmaker.com/
