you don't have 10.6.4 DVD so yes that would. People have been able to request OEM DVD for 2010 Mac Pro model in the past when they came w/o though don't know if they still would.
If it boots it will be able to receive updates based on whatever OS you have.
DVDs with 10.6.4 or later are MIA and the only other options was the SL+Lion USB flash device.
