The 2 best choices for Unreal script editors are.
I highly recommend that you use Unrealscript Studio. It has a working debugger, inteltype, and text formatting are supior. It is a plug in for Visual Studio. Visual Studio can be acquired for free through MSDN Academic Alliance
Mutators are an excellent place to begin when first starting off with unreal script. Mutators are small chunks of code that change small elements within unreal. An example of a mutator would be big head mode. Here is a good intro tutorial giving unreal a film noir look.
There are two ways to export the unreal script. One is to open the unreal editor, go to the generic browser, and select export scripts. My prefered way is to go to the epic's webpage and download them there. UnrealScriptSource 1.3
The computers were given a new image before the Nordic Game Jam. Therefore Unreal Script Studio does not work yet. The IT dept is busy installing serial numbers and Unreal Script Studio. Unreal Editor works fine
Networking is by no means a trival task in Unreal 3. Fist you are going to need 2 computers. The reason for this is in a 1 player game your computer acts a server. Most of the strange bugs you will encounter will have to do with client side replication. Before you start coding, take the time to read what UDN has to say about networking. Also check out this post on the Unreal Forums
I think the key to remember about Unreal networking is to remember that it is a client server architecture. In this architecture the unreal engine trys to minimize the amount of data that is passed to the client computers. Unreal does this is a varity of ways. Two of the main ways the engine achieves this is by 1) Only sending information about Actors that are relevent to that client. 2) Simulating functions and events on the client side.

Here are the 3 projects I mentioned in class. They all pretty much all do the same thing, they are just different approaches. I think the mixing the event driven and using the states is the best approach.
The question has come up what is the easiest way to map keys / controller buttons in unreal. I recomend you use ineractions. They are not well documented on the web. So here is an example file. Note that is is multiple classes that should be in different files. Hit me up if you have any questions.
