As for facing only one side to their host star, that's also less of a problem than you might think. On earth, different temperature zones (equatorial, tropics, temperate, etc) are arranged in stripes at distances from the equator. On a tidally locked planet, they'd still exist, but as concentric rings, much like a target, with the bulls-eye facing the star. So you'd get the same diversity of zones, they'd just be arranged differently.
None of that is to take away from your larger point - right now, we're only just moving the issue of "is there life elsewhere?" out of rampant speculation and into semi-informed speculation. But i'm excited to see how much more informed it gets over the next few decades.
