I really don't think anyone knows what ATP was originally used for, but your hypothesis is probably as good as any. I've never really delved into the early life theories, since I'm not sure how much proof you have for any scenario. I do like the self-catalytic network concept though.
It is exactly this sort of multifunctional use of molecules in biochemistry that showed me the inherant beauty of life at a molecular level. Like how many of the intermediates in the Kreb's cycle are very easily converted into amino acids, and amino acids funneled back into the Kreb's cycle. Its all about moving both molecules and energy around. It certainly made learning all those metabolic pathways a bit easier

Re: Ah!
1975 is ancient history in biology, though biochemical pathways were probably mostly characterised by them. My old textbook was Biochemistry by Stryer. Molecular Cell Biology by Lodish et al. is probably a better all round textbook however. Not so much emphasis on biochemical pathways though.
