I'm sure this question must have been asked before but I can't find it. I'm assuming that the title tag is far more important than the page's url.  Is that correct?   Does the url have any relevance to Google?

In running one of my campaigns in SEOMoz Pro, it was recommended that I reduce the amount of times a keyword is used to 15.  On the actual page, there are fewer than 15, but when you include the number of times it is used in drop-downs from the nav bar, the number is 53. I know there is really no hard and fast rule about how many instances of a keyword make for keyword stuffing and the drop-downs only use the term where needed.  Without it's use, it would be difficult to navigate the site. Is this a problem or should I focus on more important fixes?
