Your question is not easy to answer mainly because you haven't explained it in detail. A key question for you: which regression approach/method do you want to apply? Your decision on regression method has impact on how your factors/components should be calculated. In general, there are two ways for factor/component scores; either independent or correlated. There are different methods for calculation and they certainly serve for different purposes. Obviously, the relationship between your factors/components can influence your regression outcomes. You need to know what do you want to get from regression so that you may work 'backward' to score your factors/components.
