Hi Dakota,
Welcome to the FISD. If you haven't already noticed, there is a certain protocol that we follow here when it comes to recommendations for certain types of armor.
You won't see anyone posting a reply to your questions about armor with a simple, "here bro, X armor is the best and here's the link"... that won't happen here. And you can't post a I want to buy X armor thread because that's against the general rules here. So don't get frustrated in your search. You might seek out the detachment leader or even his executive officer...both individuals are knowledgeable and experienced.
One recommendation was to visit Star War Helmets.com. There you will see several different helmets from different makers. Good background info to be had there. Doing your homework will result in a more successful and pleasant armor purchase to be sure.
Have you tried contacting the Southern California Garrison for assistance? I'm sure there are numerous individuals assigned there who might be able to answer all your questions. And, you can always PM anyone of the troopers here for their personal recommendations off-line.
As for me, I'm 5'6" and I started with FX armor. I stayed with FX armor for a couple of months until I found a movie-accurate armor maker known as TE. I now wear TE armor exclusively...but I also have AP & GF armor as well.
See ya around the campus!

ePS: Also, the "size matters not" post was not intended for you - just an acknowledgement that the ANH-type armor that is available out there in the galaxy is indeed better for us "vertically-challenged" troopers.
