People do both! It's honestly up to you and the people you RP with.
I will say that having the fancier gear can help sell a role better, but that's a matter of personal preference. As seen throughout the game, there are plenty of NPCs wearing a variety of outfits who all do the same jobs. (Unless say, you want to be a chocobo porter. Then I'd probably recommend trying to get the mask somehow).
As far as in-game resources showing IC resources, some people do it, others do not. Most of the date/RP auctions are ICly OOC and do involve real gil, but that's because most are used as gil fundraisers for housing (when or just before available). The event organizers will usually state whether gil is in-game or IC though, from my experiences.
