I actually didn't realize you'd made another thread in a section I could comment in! I saw your other one and wanted to. Awesome truck! You've done some great work there.
One thing that immediately stands out though... Be wary of that Optima yellow top. Especially considering it looks like you've got a considerable amount of amperage draw in your stereo. I used to use them religiously until they were bought by Johnson Controls a while back. After they moved production to Mexico my red truck managed to kill two of them from normal usage in about six months. I switched to Odyssey and have been very impressed with them.
EDIT - Also personally I'd think about eliminating that capacitor. I've run them before and they tend to create more problems than they solve IMO. Once you get a nicer alternator I'd definitely ditch it.
