Human Factors; Procedure
Set up for runway 12 ILS; ATC changed us to runway 9 and cleared us to intercept final and cross HODLE at 3000 ft. I initially set up ILS LOC for runway 9 in the box and the aircraft was intercepting. I started to set in the RNAV (GPS) 9 in the box while descending then the first officer took over to set the approach up. When it was inserted the autopilot disconnected. I flew the airplane manually. I continued to descend and received a low altitude alert at that time I went to toga and back to climb to level then flew manually to touchdown. When I went to toga a container in the galley fell down and hit the floor. Upon arrival the flight attendant said I did not give the prepare pa which was missed because I was making my first runway change and getting prepared for that. My worst day flying ever! Should have asked for a vector to get more time for preparation. Should have gone around the moment things didn't look right. Should have asked for our expected approach to allow more prep rather than anticipating and being wrong. Should make the prepare PA more ahead of time so it doesn't get overlooked.
A319 Captain reported receiving a terrain warning while changing the FMGC from ILS Runway 12 to the RNAV Runway 9. TOGA thrust is used momentarily to recover and an object is heard falling onto the ground in the galley. The approach is continued to landing. A Flight Attendant stated that no prepare for landing PA was ever given.
