Not taking whey is fine as long as you get a decent protein intake from your diet. 0.5-1 grams per body weight pound depending on how often and hard you work out. Whey just helps reach that amount in a more convenient way.

It's good to pay attention to what you're lacking in your work out. It's pretty much Arnold's approach for beginners and intermediates; just go work out until you start seeing changes in your body, and depending on those results you can make adjustments to your program to work on your weaknesses.
