can I bring my package with me and ship from this location? if so, can I pre-print labels?

Yes, you can ship from the customer center. If you have a printed lable already on the package, you can also drop it off at Ace Hardware, a Dropbox if it fits, or find a UPS driver and give it to them (source: I am a UPS driver)

Yes, customer counter opens at 3:00

Yes definitely
