You've asked 7 fairly abstract questions, Armando :-)

The problem with abstract questions is that readers can't even begin a response without a dozen "ifs, ands, and buts", and usually they won't bother. Please try to post your situation -- who you are, what problems you are having or what you are doing that motivates you to ask these questions -- and hopefully we will be able to help.
