I was running exactly the same as you, I was tempted and bought Zone Alarm Security Suite. I could not get it to work properly, it kept crashing my computer. Zone Alarm Support couldn't find the answer and gave me my money back. I have now reverted back to all of the free versions of security you mention with no trouble. I am not suggesting you will have the same problem, but after all the hassel I had, I am not sure that even if it all works that it is worth it. You are well covered, why pay extra ? even though it sounds a good deal.
