People sometimes don't feel like reading a long post and answering tons of very newbie questions. BP.net is a great resource, but it is important to learn how to use it. Search for a caresheet online first, then another, then another, etc. Read read read everything you can first. I think all these questions can be answered there. Then if you do not understand something specifically, then search this sight. Then if you can't find it, you could ask and someone will be happy to give a quick response.
