I actually don't read that as a paradox. The sin of the parents have consequences that carry over further than just their own generation. Additionally, Jeremiah 32:18 ("you repay the guilt of fathers to their children after them") doesn't mean that the guilt is being transferred, but rather repaid.
I don't see in the passages that you quote where every person will die for his own sin -- in fact, that goes against my understanding of the Old Testament, where they were required to make sacrifices instead (at least the people of Israel). The potential paradox that I see stems from the last passage (Ex 20:5-6), where God "punishes children for the sin of the parents [...] but show[s] love to a thousand generations of those who love [Him]." However, it really isn't a paradox, because it's quite possible to punish (read consequences), while still showing love (and indeed blessings as well).
I find family analogies to be particularly applicable in situations regarding God (He's our Father in Heaven, after all...). An example of this situation would be the loving father (earthly) that had to punish his children for their disobedience. He might use the rod, or take away privileges, but still loves his children. In fact, even while taking away certain privileges for the disobedience in this example, he could still reward current good deeds with other rewards.
