Just everything since you last patched the game. If you have never patched it, then I believe you'll need all of them.
There's a bit of a problem with this approach though on a college network, you'll still need to connect to "confirm" the patches, it takes a second, it may or may not give you a problem.
If it does you can try using a VPN to connect briefly to get a confirmation, then it will install the patches.
The best way I've found (and what I do when my girlfriend who lives on a University campus has to update) is to get someone to share the actual files that were changed/added since the update. You literally go into the game folders in the C drive and either use a program or manually find what files and folders have changed, and also the patch logs in the patch folders, then send them along.
You'd need a friend who lives off campus to do this for you though.
The reality is it blows *** to play this game on a campus. Try a VPN, it's probably the best solution. Or just bug the ******** in your IT department until they open the ports for the game.
