As for doing well in combat - that's more of a science than you'd think, because D&D 3.5 is extremely complex when it comes to creating optimal characters.
If you want the simple approach - one somewhat imbalanced feature of D&D is that strength boosts both your damage and your ability to hit enemies. If you're creating a fighter of almost any kind - and you want to optimise output, you need to focus on strength after having covered what else you need. If you go dual wielding - you'll need some dex for those feats, or you can pick a Ranger level to get them for free (IIRC).
But the super simple approach is just to go Fighter all the way - and focus on Greatsword - as it's the most powerful weapon in the game, and STR bonus gives you 150% damage - because you're wielding the sword in both hands. Pick obvious feats like Cleave, Great Cleave and Improved Critical - and you'll be able to do well in the vast majority of fights. Use your party members to cover the tricky stuff.
