I can also recommend the Scottish Highland Gift Shoppe. They were able to hook my entire family up with kilts in our family (Rennie) tartan.
Their prices are definitely higher than online for a bunch of things, but they're friendly and helpful so you're paying for that I 'spose.
When I got my kilt I asked about purchasing one of their rental prince charlie jackets once they're retired and the price they quoted seemed pretty reasonable, although ultimately I decided I didn't need to own such a formal coat.
I ended up getting a crail jacket from
http://www.thescotlandkiltcompany.co.uk/ and am very pleased with it. I ordered one size up from my normal jacket size and it fits pretty much perfectly. Coincidentally, my dad ordered a crail jacket through the highland gift shoppe....and received the exact same one I got online (but for a fair bit more $$$)
As far as kilt nights around here, haven't really heard of any. My dad and I (we can't even get my brother to join us....) have gone for a pint kilted a couple times, but that's about it.
Definitely something to consider though...
