I don't think this is correct. I've never heard of any evidence for pro-aging genes, but I have read molecular biology rebuttals against this theory (Stephen Jay Gould or perhaps textbook sources, though unfortunately I can't recall well enough to cite them).

You don't need extra genes or information to prefer organisms that age out of reproductive fitness. If advanced age during reproduction confers lower fitness, then the offspring are automatically less fit. While you could argue that there would be a competition for resources amongst the young offspring, this isn't much different than other scenarios that produce less fit or disabled offspring.

True, you don't need extra information to prefer organisms that age out of reproductive fitness, but you might need extra information to ensure a timely death. It remains to be seen whether aging is just due to entropy or that regenerative processes are programmed to stop after a certain amount of time. Programmed death confers very specific fitness advantage to one's offspring as you're no longer competing with them for resources.

The sharing of genes within a population creates a nice analogy between the population and a single organism. Programmed death for members of an organism is a standard feature of evolution. It's not implausible that such a feature exists at the level of population as well.

This Wikipedia article has a review of several evolutionary aging theories:

None of these has been proven or widely accepted, and the entire class of theories has many rebuttals. They are interesting to consider, though.
