In the back room of the wild surge inn you'll find ovens. Healing potions can be purchased from any temple... or some PC's who make them.
Just a future note, most everything you want to ask that starts with a "where is" or a "How do I" can be RP'd and is a lot more fun that way, as much as I like to lurk on the forums, I'd rather someone new walked up to me and asked me in game.
