Yes, FF Tactics is mostly sequenced. There are a few streamed/XA songs, but only a few. Squaresoft tends to make the opening and ending songs streamed, a few in between streamed, and the rest sequenced in all their (newer) games.
Anyways, to convert PSFs to WAVs, thus being able to burn to CDs: open WinAmp, go to Preferences, select Input, select Disk Writer, and set the path. Now go to the playlist, take off shuffle and repeat, and start playing the first one.
And please don't try to say you line-in recorded them.
I can tell the difference fairly quickly between a line-in recording and a Wave-out PSF
