Odjn Ryu: In case this helps anyone, I've put together two specific guides for Breath of Fire IV:

Fish and Manillo Shop Guide

Stoll 80 Item Checklist

nogaruda: Thanks for it. A minor correction: the Firangi sword in the Shyde table in the Fishing guide is missing the "+1 hits" description. I noted it just yesterday, for a moment I thought that I was looking the wrong item :)
