If there were another resistor parallel (R3) with R2 in a circuit to work out the PD across R2 do you include the resistance of R3 with the parallel resistance formula or is just the ratio of R2 and R1 resistance?

Yeah if you have a resistor in series with a pair of resistors in parallel, reduce it down to two resistors by using the parallel resistor formula on the pair and then treat it like a normal potential divider
