Please help a Newbie!!!

Hi- I'm new to Flight sims and I was wondering if someone out there can help me?? I'm looking to learn how to fly a T-6 Texan II because I will be attending USAF flight training. I think this would be an excellent tool to orient myself with the aircraft. My questions are:
If I get FSX, is there a T-6 Plugin? I think I've seen one floating around that works with FS 2004, will that work? or Do I have to get FS 2004? Same question for 2002? are the plane plugins universal with the newer software? Anyone know where I can get my hands on a T-6 trainer at all?? Your help is GREATLY appreciated!!!
