I know there is a required 2GB memory upgrade to go to 8.3. 

Is it possible to do the upgrade in the following order, to minimize downtime?

1 - install 8.3.1

2 - shutdown the ASA

3 - install memory upgrade

4 - power ASA on to complete the upgrade

Or do I have to install the memory first and then do the upgrade?

check the cisco website for ram requirement for that IOS, i tried upgrading my 5520 from 804 to 8.2...something and when i rebooted the device , it showed me error for not enough RAM  ( i have 512 mb ).

Please check that out before you upgrade.
