Welcome!
You're right about the teflon. It will interact with lye and start to flake off. Fragrances can accelerate trace. Just make sure they are safe for soap, and not for candles only. Our web hosts at BrambleBerry
http://www.brambleberry.com/ have many fragrance oils that are safe for cold process soaps.
Don't shrink wrap your CP soaps til they are fully cured. They need to breathe and more water needs to evaporate. I would get a few batches under your belt before you start to sell. I don't know where you live, but you might need a business license and definitely a liability insurance. It doesn't matter whether you sell at markets or online. 30% cocnut in your recipe will be pretty drying. Go to Miller soap
http://www.millersoap.com/#Soap%20Contents and take a look at some of the recipes there. I would start w ith small batches, so you don't waste your oils or butters.
