What to keep and sell to people and what to vendor?

[Buffalol]

Last night I found a few wooden armor pieces and a leather armor recipe.  I haven't seen where people usually setup shop, so I'm curious what should I be keeping and what should I be vendoring?  I assume I should vendor the wooden armor since everyone gets that during a quest anyways.

I would keep recipes of mats that drop and soul shot/spirit shot recipe's as dwarfs are gonna want to pay for those. As you become a higher lvl you'll learn what to keep and what to dump.
