Damn, well Rasetsu made me reconsider a bit. Despite often bringing it up, I'm surprised I didn't note dialetheism in response to Chad's #6. However, I think by #8 he means that if a series has no beginning, there is therefore an infinite number of members in that series, so there is no end since at any particular point you still have an infinity prior to it, hence infinite regress and no end. Of course, there is the infinitist position in response to Agrippa's Trilemma so yeah.
