What equipment set for a Baldur's Gate: Enhanced Edition Archer for highest damage output?

I am currently building a modded saved game for Baldur's Gate: Enhanced edition (using EEKeeper) to play when patch 2.0 releases later this month. Because I just want to play it for the story and not for a challenge, I want to make my character as strong as possible before really getting started with the game. I will also be playing this in Story Mode (which is why I'm waiting for patch 2.0).

I have already set all my stats to 25 (which I understand is on the level of the strongest deities), but I also want some gear to go with it. However, since Baldur's Gate has a large assortment of equipment, I'm having trouble picking out the optimal items for highest damage output. What doesn't help is the fact that, as an Archer, I can go for multiple weapon archetypes: longbows, shortbows, composite longbows, crossbows, slings,... and each of them is calculated separately. They also use different types of ammo, but only bows have a quiver that gives an unlimited amount of ammo.

Assuming I want to go for bows in general and limit ammo to the Quiver of Plenty so I don't run out of ammo halfway through a dungeon, what gear gives me the highest damage output?

The current set I got:

Helmet: Helm of Balduran;
Armor: Shadow Armor +3;
Gauntlets: Legacy of the Masters;
Ring: Rabbits Foot;
Ring 2: The Guard's Ring +2
Amulet: Periapt of proof against poison;
Belt: Belt of inertial barrier;
Boots: The Paws of the Cheetah;
Cloak: Cloak of Reflection.
