You really need to start a new thread to get better answers. It's never a good idea to ask an unrelated question in an existing thread -- people who might have good answers for you might not ever know about your question since it's buried in this unrelated discussion.
Also, may I gently suggest that you slow down a bit as you're writing? You are likely to get even better advice if you can make it easier for readers to follow your thoughts and clearly understand your questions. Use good punctuation, avoid run-on sentences, break your sentences into short logical paragraphs, and ask clear concise questions.
