You can find armor and weapons in the Wikis, from there I usually get my infos. But a compact guide with recommendations, why not?
With weapons it's not that easy. It's always interesting to hear the opinion of others, for example about 2d6+1 vs. 1d12+1, or 2d6 + x damage vs. 2d6+1 (+ spell), what's better. I for example never use weapons which can backfire (the flail or the robot's glaive) or look ugly or shouldn't be there (like Everburn), and I prefer the boring +1 weapons generally.
