Please limit each post to one question so it's easier to follow. You can post more than one question, but just do so in a separate post so everyone can easily see questions then answers. FYI, I work from the bottom (where the first questions were asked) to the top when I start answering, so be sure to scroll down to see if your question has already been asked/answered.
