Talking about anything regarding Ichigo's power in comparison to Yamamoto's is pretty much pointless. Saying that Yamamoto is stronger than him is pure conjecture, all things considered. We already know that Ichigo has deep wells of power and a wildly fluctuating spiritual pressure. After what he did to Aizen, we might as well throw our arms up in the air - calling Plotkai doesn't do anything to help, though.

As for Yamamoto's state when being killed, it is pretty much irrelevant - he was killed with one blow. That much would not have changed regardless of how beat up he was, because the nature of the attack ensured a kill. I'd conjecture that Yamamoto had toasted himself with his Bankai a little, but even that doesn't matter. As for why he just stood there and took it, well, we already know what was going through his head in that instant.
