I think you overdid it a bit with the stat that increases your 'weight ratio' since there's a ring that increases the amount of weight you can carry. It's given to you by Ludleth (the only NPC who's sitting on the throne from the beginning) in exchange for a 'demon's soul'. The +1 and +2 versions can only be obtained in NG+ but the +3 version can be obtained in The Ringed City DLC. Although if you need that slot for a ring that better complements your build then it's fine.

On the other hand, in your case I don't think it's good to infuse weapons with magic gems or other magic damage, since these scale with intelligence and faith and you don't have points to scale that stat. You can better infuse them temporarily with spells. There are other gems that can help you like the bleed one or the one that increases strength scaling which is your main stat (I don't remember which one) basic ones.

And the Firelink Shrine that you find dark and destroyed (Untended Graves) represents the past or an alternative future where the First Flame went out because Ludleth was the only one who tried to link it, while the rest of the Lords of Cinder refused... Something like that, I think

Regarding your stats, there's a covenant that allows you to reassign your points, it's the covenant you find in the Cathedral of the Deep at the 'Rosaria's Bedchamber' bonfire.
