If all technical knowledge was lost tomorrow, and there was still "a next generation" to give this data to... then I should think that as much solid information as someone can get about whatever gods/aliens did this, and specifically the reason *why* they did this (if available) is the most important thing. If we, with our current technological state, cannot see this coming (SETI's existence pisses me off)... then clearly, as we found all this other stuff out beforehand, that is the most needed technical knowledge, even if it is only technological in the information of specifically what happens when a certain thing is done, and especially why.
Alternately, if we don't examine your question to the conclusion that we should make... then I would say that I would have the data that clean hands and medical equipment save lives. Going to the doctor should not immediately put you into contact with diseases and whatever else people have been carrying. I believe this to be tantamount to the scientific method's re-advancement. If half of the people who visit the doctor/hospital do not die, then that's a significant portion of the population out there capable of making discoveries.

Please give me a home where cloud buffalo roam
Where the dear and the strangers can play
Where sometimes is heard a discouraging word
But the skies are not stormy all day
