It can be set using T-SQL or you can set it in SSMS under Properties, I think Advanced (I'm not at my server right now) and maybe you should throttle it down to 2, and see how that goes.  Of course you can check it out in BOL, but I know how tight you time is, I was given the tip by a someone else and it did work a charm on some of our servers (I manage 1900 servers of various DB sizes, all the same DB though and all with the same hardware/software config) that had the larger DB sizes.  Test it out, see how it goes.  It sounds counter intuitive, but it prevents one query from taking control of all of SQL Server and holding everything else hostage.
