I don't know what's "too much information at once", but if you find yourself getting lost, then read it top to bottom and whenever you're done with a spoiler, close it and continue to the next.
As far as the basic combat stats go, "Powers, Abilities & Special Properties" and "Hindrances" are the spoilers that interest you the most (you could keep the inner spoilers closed).
The rest is mostly campaign and storyline stuff.
