Cost of debt in a DCF model and target capital structure

Hello Monkeys,
Can anyone provide some insights on how to find the cost of debt for a firm and the target capital structure.

Cost of debt is the interest rate to borrow. However, a company may have all kinds of liabilities with different rates. How do you find the cost of debt?

Rosenhaum's guide states that usually the optimal capital structure is used. However, how do I determine the optimal capital structure?

Thanks in advance
