You don't have to worry about the outstanding amount other than using it to calculate how much credit limit you have left to avoid going overlimit and getting charged the overlimit fee. Otherwise don't worry about. Just pay your statement balance in full. I paid my credit card on the due date itself. No difference.

But, its best to pay your other bills 1-day or 2-day after the credit card billing cycle. That way bills like streamyx, maxis, astro can be paid earlier. No difference on using your credit cards to pay bills now or two weeks later as it will still appear on the current month statement but paying earlier on these accounts will ensure prompt service whenever issues arise.
