yeah i think it's generally accepted that lifting weights is good for you - but if you're not interested then no point in forcing it
my goals have never been heavily skewed enough toward cardio/stretching to dedicate much to them... running is certainly one way to do it. for stretching - i've heard that pavel's 'relax into stretch' is good reading material.
