Ugh, both names are pretty weak. I don't like the "o" in MindOMeter at all. I do own a site with an "o" (tagomatic)" but it flows in the name. Not sure mindometer flows when you say it. ScoreBean, still pretty weak. Just not a great name. Maybe start a naming contest where you can really get some creative people coming up with names. Try Naming Force.
Goals are a way to track success when it's measured by a > b > c page navigation. For example, a user comes to your home page, clicks your newsletter sign up link, signs up and is sent to a success page. The goal would be called "Newsletter Sign Up" and you would set the path of these pages (home > sign up > success) for the goal and Analytics would track these successful goal completions.
Only thing I hate about GA goals is that it doesn't work well when you funnel users from different pages into the same page (payment). So if you want to track different types of sales or different types of sign ups that end on the same page, it just tracks them as the same goal (or same number of completions). I haven't found a way around this.
You have to be careful, though, nowadays. It used to be that it was smart to link to sub-pages with your main keyword, but with Google's now ultra granular search results you could accidentally push your sub-pages to be more "relevant" for your keyword than your home page. I know because it's happened to one of my sites. In some instances this would be OK, but if you want traffic to be directed to your home page for your keyword, be careful about over-SEO'ing your sub-pages. Just another thing to think about...not disagreeing with internal linking with your keyword.
