Upon entering the labyrinth, the hero, you, was greeted by a gate. The gate is next to a waterfall where the contents of one pool flow into the next pool.
The gate was still until your approach, and then it stirred. "You must tell me the answer to my riddle for which I gives three clues, each with a key to the clue. Putting all the clues together will give you another riddle and the answer of that riddle is what will open me."

Hahaha! You thought it would be that easy! But, no, please be considerate to your ancestors and rank before you use the keys! Oh and pardon me, I seem to have left some junk about. And did I mention that I like movies more than books?
Taken from @Alconja's answer below, don't read if you want to solve the riddle yourself.
Alconja correctly identified the keys as powers of 2 :8, 4, 2
Then he came very close to getting the second clue, the ancestry. The gate is the root, therefore the first word jumble is 1, the second is 2nd and the third is the 3rd ancestor. That means skip the first, second and third words of each jumble and take every 8th, 4th and 2nd word respectively after that. This removes the jumble and yields the final riddle. However!! The 3 lines of the riddle are also ancestors. Take the answer from the first and apply it to the second, and the answer from the second applied to the third will yield the final key to the Gate.
I apologize if this was too difficult, that is what I intended.
