For straight-up JRPGs, try Wild Arms 2 if you're a fan of the first one. It's different in some ways, but you'll probably still like it. I haven't played it since it came out, though, so maybe I'm misremembering its quality.

Also, Legend of Legaia. A nice, traditional adventure with a unique turn-based "fighting" game battle system. The trick of it all is finding combos and then finding ways to link them together within a limit of inputs. As you level up, you gain more leeway for inputs, but equipment also plays a role in the "stamina" per punch/kick. Check out some clips on Youtube if you're interested.

You also can't go wrong with either of the two Lunar re-releases for PSX.

As for tactics games:

Vagrant Story 1 and 2
I'm going to go out on a limb and assume you mean Vandal Hearts 1 and 2 and not Vagrant Story. There is only one VS game and it's certainly not a tactical RPG.

The obvious choice for this genre is FF Tactics. From what I remember, Front Mission 3 is also a good time. I don't have a lot of experience with the genre, so others around here probably have more to suggest to you.
