You will only need to remove the black plastic trim covers, coils and the 18 (+/-) bolts that fasten the valve cover to the head. I didn't replace the rubber donuts on each bolt, but I would recommend it.
Now would be a good time to strip and paint your valve cover if it is peeling as is typical. I used high temp paint from Advance Auto and it matched the original color almost perfectly. Be sure to prepare the surface well before painting and only apply light coats at one time per the spray can directions or you will get orange peel. I wanted to have mine stripped and clear anodized (or powder coated) but time and money would not allow.
After you get the valve cover off, I would inspect the cam lobes for any scoring and wear. Also check the secondary chain tensioner. It should be putting enough pressure on the secondary chain so that there is no visible chain slack and gives a pretty good resistance when pressing down on the middle of the chain. I have found the timing chains to be very rugged so I would expect that the chains are still in good condition.
