Zebra Crossing is an open-source library that can help you accomplish the scanning and creating of QR codes. However, you'll have to be more specific about the Bluetooth part.

I am seeking a GKVoiceChat example for the iPhone SDK in 4.0 or later. It will surely help with my iPhone game.
There are two Game Kit samples I've seen that include GKVoiceChat.
Search for GCPing in the Apple dev forums. (I'm not posting a link because it's not clear the author wants a public link). This sample is clear and basic, but demonstrates a wide range of working Game Kit multiplayer concepts. Search back over 'all' time, and look for the 'GCPing WWDC2010 - Updated for iOS 4 GM Seed' post.
multiplayer Pong client. Found here.
Haven't looked into sample 2 much yet, but it looks pretty good.
I was wondering if there was a basic tutorial to get me started on coding a FrontRow plug-in / add-on using Xcode.
I searched Google a couple of times, but I haven't found a tutorial on this subject so far.
After some more searching, I found this Wiki-page about creating an app for the Apple TV.
As far as I can tell now, it's a good base to start a FrontRow app too.
If someone else may find a better tutorial, please let me know.

Edit:
Doesn't really seem to work on my system.
I'm building a simple Cocoa app and I want to direct the audio output to a specific device, instead of the system selected one. I know some apps, like Skype, let you select where to send the output to. How do they do this?
I tried the MTCoreAudio framework but I can't even compile my app (or their AudioMonitor demo) with it included and the errors aren't helpful (_objc_fatal). Are there any complete examples that I can learn from? So far my searches haven't turned anything up.
Thanks!
The CAPlayThrough example on the Mac Dev Center Sample Code library shows how to list all of the available input and output devices, and select a default device from a menu.
Have you looked through the sample code on http://developer.apple.com ?
Look at these projects http://developer.apple.com/mac/library/navigation/index.html?section=Resource+Types&topic=Sample+Code
Namely the DefaultAudioUnit project.
I should say that working with Core Audio is more challenging than Cocoa. Most of the API's are C-based (I find that harder). You should read the Core Audio programming guide as well to get a sense of how the audio system is put together.
