"gtst" is just what our Australian cousins call the GTS25t The R32 gtst was 2L, the R33 is 2.5L, hence GTS25t.

Standard, they all have an LSD (no matter what that dirty bizkit said ), and a driver's airbag. Series II (mid/late 1996 on) have 2 airbags. All have HICAS

Options were ABS (though apparently the majority of them have this - mine doesn't), and an active LSD like in the GTR (very rare). I don't know what other options there were.

in 1998 xenon headlights were added.
