If they aren't asking you for the additional docs, before your AOR is sent, then i'd prefer you hold on to these docs, just so that your docs dont get mishandled or lost in transmission.
Once they send you the AOR then you can forward them these docs. PCs, T4, NOA are all additionals docs that helps the officer to verify your application.
