New to the game, but catching on.

I was able to outfit my fighter with +2 Fullplate, Towershield and Longsword using the Auction house.

I just hit level 4, and want to upgrade my gear. So first off, advice for a budding sword and board human fighter, and then if you have anything for sale, let me know. I don't have any items that give me deflection/holy/dodge etc. bonuses yet. I've also been thinking of using a shield of bashing...

I have about 4,000 platinum banked. Most of it I earned by selling potions of minor Mneumic (sp?) recovery on the Auction when I received them.
