Your plan sounds good. I did a similar thing recently. Signed up for the citi aa cards I think in September. Miles posted in november. Booked 150k oneworld award thanksgiving weekend. I primarily used amazon payments to accelerate the spending. My best advice is to get the points posted asap and start booking your itinerary asap to ensure you get all the routes/schedules you want. Good luck.
