1 - It's never too early to ask for a discount
2 - You can probably get 20%+ easily
3 - Discounts with FedEx run as high as 60 - 70% for high volume shippers (you're a long way from there)
Caveat: I don't use FedEx but had once had a problem with a shipment, in an attempt to appease me they offered a 30% discount.
They might require a contract (some shippers do) where you receive a rebate if you reach your volume commitment but less if you don't make the quota.
