A great bluetooth NXT tutorial can be read here:http://www.robotappstore.com/Knowledge- ... ms/92.html
It addresses the commands that are sent over bluetooth to the NXT controller and offers some step-by-step instructions for playing around with it. I recommend reading through it since it gives you some great insight into how the bluetooth commands work.
For bluetooth from NXT to NXT I was told that there was a slight trick. I believe you are correct with the thinking that there is a master / slave interaction. I'm working on finding out some more information about that, and I'll post it back up here when I find out.
Ok - onto teaching Labview... haha. I'm not one to make judgements on software packages, but I'll keep it short when I say I try to avoid labview
. That being said, there are a bunch of great tutorials about labview - probably the best would be from the national instruments website itself here:http://www.ni.com/white-paper/7466/en
If you are looking for specific labview with NXT, try this out:http://www.youtube.com/watch?v=fnqloVsSPG4

Hope this helps,
