Do you have the QR or EY freq flyer number in the reservation now? You can have a freq flyer number in a reservation and try to change it at check in, but it does not always stick: high risk

Oneworld Ruby is low status and does not entitle you to much

Note the " *In accordance with the individual policy of the oneworld member airline operating the flight" foot note

Extra legroom & seat allocation will be as the t&c's of the ticket. As a non AA freq flyer on an AA economy flight keep your expectations very low to nothing. Have you a seat allocation now? If getting EY miles is important I would forget about using your QR status to try for benefits.
