I need help on number 2 mainly I'm not sure what route to take on this. The resistor and inductor on the bottom are confusing me.

You have sufficient information to calculate the individual currents (complex form - magnitude and phase) in L1 & L2.

Then you can find the total current (complex number sum IL1 + IL2).

The total current flows in series with R1, R2, XL1 & XL2. Hence you can determine the total voltage drop across these series elements.

The source voltage is then the total series drop across R1, R2, XL1, XL2 plus VL. Again - this is a complex number summation.
