Okay, this is an older game and most people are Level 50. Although it is common for people to create new toons and level them up, they do not do them in the areas you are talking about. People who are new to the game have to start here, but unfortunately, you are one of the few.
Eventually, when you start getting higher in levels, you can go to Thidranki (level 20-24). On almost any server, this is populated. This is sort of mini-RvR for people of that level. It is a fun and exciting place, and it should be something you can shoot for.
As for money, yes, it is ridiculous how expensive things are at a low level and how little money you make. I would suggest going to the Catacombs Instance dungeons. These dungeons give aurulite and cash as rewards for killing monsters, and you can buy stuff witht he aurulite.
Try to tough it out. The game does get much better, but unlike something like WoW, where leveling is part of the game, this game really begins once you hit 50.
