Hey Chad,
Welcome aboard man! First off, jump on FaceBook and introduce yourself to the people on the Star Garrison group.
This one is open: https://www.facebook.com/pages/The-Star-Garrison-of-the-501st-Legion/155799257916211?ref=br_tf
(There is also a closed group for members)
You will find that the SA folks will be more than happy to assist you with questions and answers. Don't feel afraid to ask here and there with anything you want to know. There's some locals that will be able to help you in person. Ask about attending an armor party, I believe there is one coming up soon.
RT-MOD or the new NE may be your best bet, from the sounds of it. Take your time, enjoy your build, and as they say, "Measure three times, cut once..."
Cheers,
Steve
