Yes, L1 of the single phase supply is terminated under terminal L1 of the three phase contactor. L2 of the single phase supply is terminated under terminal L2 of the three phase contactor. A conductor from output terminal T2 is then taken to input terminal L3. The single phase load is then connected to the contactor's output terminals T1 and T3. This incorporates all three of the overload blocks on the contactor into the control circuit. With the overloads in the control circuit, if an overload occurs the magnetic contactor's holding coil will drop out and take the load off line.
See discuss question below.
yes
Power factor capacitors can be installed on a three phase motor between the motor contactor and the overload heater block.
You start with a normal one way circuit consisting of a three phase contactor and an three phase overload in series for the forward circuit. Then you add the reverse contactor in parallel with the forward contactor but with line one and line two crossed over i.e. when the reverse contactor is made, line one of the supply will be connected to line two of the motor and line two of the supply to line one of the motor. The control circuit must also be interlocked to prevent forward and reverse being energized at the same time.
Not without other modifications. The circuits used to turn the solid state relay on will not be suitable for turning a contactor on.

your not completing the circuit your only using one phase for a three phase motor

A CONTACTOR SHOULD NOT BE USED TO START A 3-PHASE MOTOR unless there is some sort of motor protection in series with it. You would need a 3-phase contactor and just connect each phase (1 wire) to each terminal of the line side of the contactor, and the 3 wires to the load side. 3 wires on the line side, and 3 wires on the load side.

it can tell you which way a motor will turn before you apply power sometimes nice to know
To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
