It's never enough to try and cripple limbs. That only means you can JUST outrun a Deathclaw, should you care to run away. Here, let me tell you what I know of dealing with Deathclaws. Fallout 3 and New Vegas has forced me to stay on my toes. But don't worry. Jack gets results.
Deathclaws
The thing about Deathclaws is also the thing about quite alot of things out in the wasteland. They find it rather hard to do anything if you are, say, up on a rock, or even just on a steep hill. The high ground is very important, Anakin. Incidentally, I would say if you don't have the Shotgun Surgeon perk, get it. If you don't have Bloody Mess, get it. Deathclaws require higher levels of damage. My courier is built for crazy criticals. He has Luck 10 and I built him for that, which means I started playing with fate more than physique. Nevertheless, the thing is that Deathclaws demand something long-range and nasty at times. If you can ever get at one from a vantage point where it can't jump, do it. Pour the juice on. Fact is, there's alot of times where energy weapons are better. This is one of them.
Blind Deathclaws
I don't care what anyone says. They aren't nearly as blind or in the dark as they seem. Treat Blind Deathclaw AS Deathclaws in action. The only thing of REAL difference is that they might have less accuracy because their vision is supposedly impaired. But then, they hear and smell, right? And they know their territory? Yeah, I don't think blindness matters. Just saying.
Alpha, Matriarch, and Legendary Deathclaw
If you didn't know they stepped up Deathclaws in New Vegas, then allow me to be the one to inform you. If you did, here's what I know.
Alpha is king of the brood. He is fast and he is deadly as hell. He can one-hit you, despite high-end combat armor probably, even when you get stronger. He's the father of the adults you've probably been seeing, noted for being bigger and faster. The Matriarch is, of course, the mother Deathclaw, noted by having horns that face backwards, not forwards. Also, she is big. You don't want to get near her. She gets special berserk powers if you kill her babies. Do keep that in mind. Legendary is like father to an Alpha, probably. About the same disign creature, but more menacing. I got rather lucky with mine. He apparently didn't see me and kept pacing around. I've no doubts about HIS power, though.
Deathclaws are usually best dealt with at a distance and especially without them knowing that you're going to attack. If you're going to attack any of these three, make for fucking sure that you are somewhere that is highly-inaccessable to them or where you can jump off a hill or something that delays them attacking you. I killed my Matriarch with a sniper rifle when she was a speck in my crosshairs, too far away for her to detect me. And you know what? I am never getting closer. Additionally, there are ideal weapons to go after for this. If you took Wild Wasteland, then you can find an alien blaster, for instance. (Take note that there is actually a laser gun with a high ammo consumption that is the same power as the alien blaster.)
