Veteran rewards are NOT preorder bonuses - they are listed in Bonus section like this:

Other Received Bonus Items
・Cait Sith Doll
・Moogle Cap

If you don't see them then either you've not registered them to same service account or you've not initiated the client download after entering the PSN code on PS3 (just cancel the download right away, no need to fully redownload). If the next time you start launcher on PS3 you'll be prompted to (re-)link your PSN account to the SE service account - CAUTION - do NOT select the "Create new Service account" option there or it will not attach to your current accoun but create a new one instead which is most certainly not what you would want!
