your gear looks decent actually and if you are fine with 40 fps you should do ok even with environmental mods and hd texture. For a lore friendly npc texture XCE is strongly recommended, grab some lore-friendly hair retex on the fly. If you are looking for something sexier or better looking for female, UNP and CBBE are some base fem body texture to start with. All of ZZjay's texture or SG texture renewal gives female some really pretty face. Alternatively use better female by bella or coverwomen. For male npc your options is limited, pick better male but careful with the nude texture, or if you just want a better looking char, use genox's male texture or urshi's fine texture for men. Combat rebalance seems like a touchy subject, i've never seen one or had one but there are a bunch of combat overhaul, namely duel or epic combat overhaul. Skyre or requirem works similarly too. Never used any of those,though Animations are falling short, the only thing i recommend is immersive animation+ xmps sleleton which gives you alternative sheath option. If you are feeling lucky, pick up Dual Sheath Redux. For that mod to work takes some effort though.
