Hi, Hope this helps, Q1: Your statement is correct. A port must still listen to BPDUs in order to detect topology changes.
Q2: According to Cisco books, blocked, listening, learning, and forwarding are valid STP stages. I haven't seen a book not list blocking. If you have one handy, let me know. Q3: I interpret BPDUs as a generic term to represent Topology and Configuration BPDUs.
