I agree with everyone above!! Excellent beginnings! You'll fit in like a champ.
POUCHES like whoa. Seriously, you'll end up carrying so much crap on you that you won't believe it. So maybe a belt pouch or two in addition to the bag you have. And honestly, don't be afraid to layer over your garments. It gets cold at night during the games, so long vests, jackets, hoods etc are going to be great additions. And the Selunari are totally a fun loving vibrant culture, so the gold is definitely not a problem. Heck you can probably add more bling (tassels or coin chains or trims to it) and it won't be out of place. BUT that it all up to your comfort level.
And yes, the glass in the lantern (if it's glass) would be problematic on the field, but if it's just in the tavern or in a cabin it should be fine depending on the chapter you're playing in... (If it's Oregon - and I've spoken to you like I think I have - you will be fine as long as it's out of combat).
