1) The fan is optional. It used to force air over the temp sensor when used in a radiation screen as on sunny days these can read a bit high.
2) The TMP36 temp sensor is to measure the temperate inside the case that the TX unit is mounted in. It's also optional.
3) The Wind vane data goes via one pair to Pins 1 & 2 and the Anemometer goes via the other pair to pins 3 & 4. Take a look at the schematic, that should give you some hints to want pins do what. Werk_AG may give a definite answer on these.
