There's a FF9 sticky, try reading that. It'll help you with configs for sound and opengl.
For opengl2 plugin, try using the config I attached. I've used that same config for FF7, and it seems it works perfectly with FF9 too.
Set the gfx RAM value to your card RAM value (red box in pic)
If it's too slow, try changing res to 640x480, and if ok, try grad. increasing (yellow box)
If high x internal res not supported, set it to 1 (green box)
Special fixes, since you're using 1.5.2, use odd/even bit hack, 5th from the bottom, and I had the second one from the top, ignore small framebuffer moves, but dunno if that made a difference. If too blurry for you, then you can modify that in-game, by pressing:
delete: brings up settings in top-left
pg up/pg down: scrolls through the settings
home/end: modifies settings
go to SL, near the end, SL = shader level, and set it to what you think looks best
This is what it looks like (2nd attachment). There are absolutely no slow downs, not even battle transitions which work perfectly too. I can't say too much though, since I've only played up to that point on that screen cap.
If it's *still* too slow, go for opengl configs.
