How would I possibly evaluate this? It looks as simplified as it can get. Thanks a ton!

Multiply both numerator and denominator by the denominator's conjugate. Remember, the conjugate of a complex number a+ib is a-ib. and (a+ib)(a-ib)=aČ+bČ, which is a real number and this is the reason for which we make this operation.
Yes, remember that you just multiply by the conjugate of the denominator and FOIL. Also remember that is equal to -1.
