Feel free to email any of the admins from this forum and we will be glad to answer your questions if you do not want to post on the forums. However, posting on the forums enables us to answer a question that many people may have, so we ask that if you feel comfortable with it then it will not only help you, but will help others as well
With that being said, you can email me anytime (my email is in my signature).
To answer some of your questions, you will not be charged with version upgrades with v1.x. The latest beta version that we're testing has the NXT to NXT enabled, and we are just making sure that this build is working up to standard before we release it.
There are many explanations in the Software Training Guide that you can access from the robotc.net root site. We are currently working on this Training Guide which will eventually become a book which can coincide (or even can be replaced) with the multimedia-rich lessons.
As far as the playtone frequency, I will pass this question onto the Software Development to gather further information.
