If you claimed the gifts back when they were given, they should still be on the characters unless you sold/gave away or dropped them. If your account was not active when they were given out, then you missed out on it.
You may well have some veteran reward choices waiting for you, but they only add up for paid time on the account - so do not expect 10 or 11 year rewards to be waiting for you.
Sadly, the SA early purchase has also ended.
