Other people have gone with fairly even stat distributions.
A little bit of everything is fine, but you will eventually be get getting a fair chunk of resistance from equipment and possibly enchantments. If you are not going to be using a bow, then there is not much point with a high dexterity.
I boosted Potion Efficiency my first game, as well. Once you get the battle tower (about another 5 levels, if you keep going), you will be able to unlearn your skills (for a price), and then just not re-learn it (potions are easy to get after you have the battle tower, anyway).
