Doing the job now, please help

What is the proper and easiest order to replace the three timing chain guides, tensioner rail, tensioner, and lastly the new, unstretched chain that I am going to feed in from the passenger side? Is it easier to replace the rails with the chain slack? (tensioner removed). Since I have never done it before, I am very leary about messing up and not having a car to drive on Monday morning. Any help would be greatly appreciated. Thanks
