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 $\displaystyle i^2$ is equal to -1.
