2001Kanji Odyssey - how many compounds/readings should I learn

I am starting with KO2001 next month. There's a lot of compounds/readings listed for each Kanji, and I am sort of overwhelmed with them. There's "Important Kanji Words" on top and then "References" with many more readings on the bottom.

I don't think it makes sense to learn all of them for every Kanji - but how to make a selection?

Any advice? What do you folks learn? Just the top part with "Important Kanji Words"?

Thanks for your help!
