Yes. UDP is supposed to preserve packet boundaries. The packet may get fragmented and reassembled at the IP layer but this is transparent (someone correct me if I'm wrong).
Correct, IMHO. UDP provides connection less services to upper levels. It exists due to the need for a protocol which avoids the overhead of connection establishment (& release) when it is not needed. Sometimes you would like to send only one packet and get only one packet in return. TCP would be overkill here.
Yeps, IP can and mostly will fragment the TPDU (unless it is very small).
