How much do you know about the game already? For example, do you know which NPCs you want to have in your party and which weapons you would like for your party members to use? For example, if you want to have Minsc in your party, I'd give him the best two-handed swords in the game and give your main character a different kind of weapon, such as warhammer or longsword. Your party composition should determine how you distribute weapons, which in turn will determine how you distribute proficiency points.

To take another example, if you want Aerie in your party, you don't need another Cleric. Here's why that might affect your weapon choices. There's one really good flail, one really good warhammer, and one really good mace in the game. Chances are, you wouldn't want to put Aerie on the front line, so instead of giving her one of those weapons (which are all useable by Clerics), you could give it to your main character. But if you chose one of the other Clerics instead of Aerie, I'd put him on the front line and give him one of those weapons instead of giving it to your main character.

You also need to consider your own playing style (like Astafas suggested). Do you want your character to use big two-handed swords? Do you want him to wield two weapons at a time--one in each hand? Or do you want him to carry a shield and wield a weapon in his other hand? There are no "right or wrong" answers.

Off the top of my head (without making a comprehensive list of all the possibilities), I think that putting three proficiency points in katanas and three proficiency points in scimitars would give you lots of flexibility. Later, you can add proficiency points to Two Weapon Style (which becomes more effective as his THAC0 improves) or put points in a third kind of weapon, such as longsword or warhammer (depending on how you want to distribute weapons among all of your party members). I don't recommend putting any points in Sword and Shield Style, and three proficiency points in each weapon type is probably optimal.

If Minsc is in your party, make sure you give him points in Two-Handed Weapon Style if you want him to wield a two-handed sword. He can also wield the really nice mace I mentioned earlier. I can't remember what proficiency points Jaheira has, but a quarterstaff or a scimitar (with shield) would be a good choice for her. There's also a really good spear in the game and you might consider giving it to her. Like everyone else, she benefits from two proficiency points in Two-Handed Weapon Style if she wields a two-handed weapon.
