Found this on a review of Market Samurai which might answer one part of your question: "Market Samurai can help you identify the right keywords to appear on Google’s first page. Yes, I said IDENTIFY. This means you don’t select the keywords. You actually look for them" If I were you I would read their reviews, this might just help answer all your questions.
