You got the better deal.
My advice, forget that bottom bracket thing and go get a cartridge BB. I have no great love for the serviceable BB's. I have several and they are not in the same category as dork disks and foam handlebar tubes, but as the opportunity arises, I usually change them out for cartridges.
You will love that bike. Ride it like you stole it, because you did.
The problem is that the shell is set up for the press in BB and it's near impossible to convert.
I emailed Tom Kellog at Spectrum with my questions and got fast answers...including manufacture date. Serial number was on the chain side rear drop out.
