I don't mean to send you away, but have you checked out the BYOAC forum? These questions you have been asking are EXACTLY what they do in 90% of the posts. Asking here is fine, but you might find all of your questions answered already in posts over there. If I were you, I would check them out and see what they recommend. If that doesn't clear up all of your questions you can either ask there, here, or both. There's a lot of knowledge in both forums, it's just that this one is primarily focussed on the FE software side of things (both the front end and getting the front end to work with other things). Anyway, just a suggestion.
