Correct. 100k miles or 100k points. Most discount fares give you one mile or half a point. Personally, if you are flying AA and in coach, go with AAdvantage. Do the platinum challenge, which will give you platinum status after 20000 discount miles, then you get 100% bonus, 500-mile upgrade accrual, and platinum for quite a while. If you get within 5000 miles of renewal (get up to or over 45000 miles this year) then I think it's worth it to just fly somewhere for the weekend and get the extra 5000 miles.
Also, you will accrue more miles with AAdvantage and personally I think they are worth more. The two advantages you get with QF is that you can take BA across the pond (which you aren't doing anyway) and you can redeem an award to take BA across the pond.
