The tutorial is based on an older version of RPH that, at the time, was a few weeks old and hence the API has changed. The RPH version from the website should be compatible with the latest game patch, so you can use that. As you noticed, some calls have changed, though. I believe the keyboard functionality is now in the Input class. There might also be a few comments on the tutorials or tutorial projects where people have asked similar questions, that might help you too. I do not have the time to update the tutorials right now, but Visual Studio's IntelliSense should hopefully help you quite a bit with figuring out what functionality is available.
