(1) I can't do PDFs, unfortunately, so could you explain what you mean here? (2) I think Grognor is talking about people's expectations of future utility. If these are positive enough, then it makes sense to endure present hardship (because by enduring it, the agent creates larger benefits on net--just in the future, that's all). That is, as long as the future will be bright enough, people shouldn't choose to die now. Such lives therefore suck, but less than death, right? And if such better-than-death lives are common, then that hardly supports "life sucks worse than death."
