There are multiple guides for ED that can be applied for the first part of DKS. There's no change quest-wise except the location of set pieces. The secrets the guides expose are still present in the fortresses although the dungeon crawl has been simplified that many hints on how to disable anti-dragon zones become unnecessary.
I couldn't find a good FoV guide except in German. Most of the secrets are in this forum, but I've compiled a text file myself. You can PM me if you want it.
Personally, I don't see a need to hunt for secrets in the FoV part of DKS. The best weapons can be purchased directly from vendors. If you already know how to obtain the FoV armor sets, you already have the best matching armor. The real worth of a FoV guide would be to get that very last skill and stat point.
