Sell polo on eBay, look up Kent Wang polo without label. Not that I condone polo shirts because they're not my style.
Edit: Isn't the logo embroidered? It'd be a pain in the ass and my tailor would fuck me up for asking. But go for it.
You'd be better served getting a regular tan or natural leather belt and distressing it yourself (through actual use). Don't care for the shoes, but if you love them that's cool. Replace the laces with some matching dress laces ASAP. Do that and they should go fine with most jeans and chinos that aren't black.
Guess it's just cordovan,
I guess having a smooth texture would be too formal for the boot anyhow.
Yes, no, no.
Archival makes a good webbing belt comes in Natural, Tan, Dark Olive and Navy.
I personally wear a custom motif belt from Leather Man Ltd its like $28 on sale right now.
