There are some decent books on Norse myth - Kevin Crossley-Holland's Norse Myths, and Osborne/Howell's Favorite Norse myths to name a few. Their creation myth is a bit bizarre: From the cold realm of Muspell and the fire realm of Nifleheim emerged Ymir the giant and a cow. Ymir drank the cow's milk to stay alive. From his armpit sprang Ask and Embla, the first "people" and they had Bor and Buri - and from one of these, can't remember... came Odin.
Ymir's sweat became the ocean, his bones became the hills and mountains, his teeth became the cliffs, and his hair - the vegetation and trees. (Reminds me of Panku from Chinese myth - where his eyes become the sun and moon, blood the ocean, etc.) Two groups of Gods emerged - the Aesir - the pillars of the world, made Middle Earth (Midgard). They stationed four dwarves in each corner to support the heavenly vault (Asgard) The four dwarves were called: Nordri, Sudri, Westri, Austri (North, South, West, East - getting information from the four corners of the world - N.E.W.S.) The other group of Gods were called the Vanir - the peaceful Gods - fertility based.
Balder's Death is probably the best Norse myth for me, because it contains so much symbolism, current environmental issues, and basic every day concepts that stand the test of time (parent's love, death of child, mourning, etc)
I'll bet if you google the Aesir or the Vanir you'll get some good stories. Also, Yggdrasill - their world tree (made up of Nine worlds) is similar to some Celtic/Druidic worship of trees.
