Anything and everything in the LOS can and probibly will high profile.
The exams do focus on a few major things, i.e. one year they threw a dozen taxation questions on, other years they just love off Dupont and then there is the ever constant LIFO/FIFo from what I hear. Economics does have a bit to do with Foreign exchange and the olbvious other material, Quant is relatively simple, from the people i talk to. Read the back posts, there are many with past level 1 candidates recanting their experiences. But expect anything, for instance last year I heards GIPS got hit hard.
Bottomline, there are no guaranteed short cuts, just study your ass off and try to master EVERYTHING!
