I was going to post a lengthy post about all of this, but Sasquatch pretty much nailed it on the head. I just have a couple things to add about this.

- The Omega Ruins. Fight there for a while. You'll stock up on level 3 and 4 key spheres, and a bunch of sweet weapons that you can sell for lots of gil. If you're not at the point where you can comfortably fight there for a while, then go to the Hidden fayth and fight one of the ghosts for a No Encounters armor. Stick by the save point, get into a fight, then equip the No Encounters armor so you can go save. Lather, rinse, repeat. (Just a side note: First Strike is necessary on at least Tidus, and provoke can counter Great Malboro's Bad Breath, and is your only real defense against it.)

- They can also be obtained by bribing Chimera Brains. It's about 200,000 gil for 2 spheres.
