Narrative:

During descent to pit; we briefed and expected an approach to runway 28R. The ATIS was broadcasting approachs to runway 28R and runway 32. We were never told by approach which runway to expect. We were given what we thought was a downwind vector. Then we were given a left turn heading 350 degrees; maintain 2500 ft until established (we were at 3000 ft); cleared ILS runway 32. We tried to change the ILS frequency; FMS; slow; configure; and brief the approach to runway 32. We saw the runway and started the descent. At this point we were high; fast; flaps 20 degrees; gear down. Then we got a 'terrain' warning. West decided to do a go around rather than attempt to salvage the approach. I should have asked which approach to expect. I assumed runway 28R due to the fact I usually get runway 28R when going to pit and the way we were being vectored.

Title: A CRJ200 EXPECTED AN APCH CLRNC TO RWY 28R; BUT WAS CLRED FOR A RWY 32 APCH; RESULTING IN A HIGH APCH AND GAR.

Narrative: DURING DSCNT TO PIT; WE BRIEFED AND EXPECTED AN APCH TO RWY 28R. THE ATIS WAS BROADCASTING APCHS TO RWY 28R AND RWY 32. WE WERE NEVER TOLD BY APCH WHICH RWY TO EXPECT. WE WERE GIVEN WHAT WE THOUGHT WAS A DOWNWIND VECTOR. THEN WE WERE GIVEN A L TURN HDG 350 DEGS; MAINTAIN 2500 FT UNTIL ESTABLISHED (WE WERE AT 3000 FT); CLRED ILS RWY 32. WE TRIED TO CHANGE THE ILS FREQ; FMS; SLOW; CONFIGURE; AND BRIEF THE APCH TO RWY 32. WE SAW THE RWY AND STARTED THE DSCNT. AT THIS POINT WE WERE HIGH; FAST; FLAPS 20 DEGS; GEAR DOWN. THEN WE GOT A 'TERRAIN' WARNING. W DECIDED TO DO A GAR RATHER THAN ATTEMPT TO SALVAGE THE APCH. I SHOULD HAVE ASKED WHICH APCH TO EXPECT. I ASSUMED RWY 28R DUE TO THE FACT I USUALLY GET RWY 28R WHEN GOING TO PIT AND THE WAY WE WERE BEING VECTORED.
