Does nobody ever keep a stash of money in the bank and then buy basic gear from shops? I know I used to, back when I was getting full looted and people weren't generous enough to give me stuff.

Most of the shops in Galadon are there for basic stuff so you can buy it then go out and upgrade. I mean, most of that stuff isn't worth keeping once you've gone out to get better, but it certainly helps you get that 'something better'. Other cities have shops with the basics too, and some even have really nice stuff for sale, though at high prices.
