I can not tell you how helpful having the chilton (or Haynes) manual is for this kind of stuff. Gives you all your tourque specs and what the bolt tourque patterns are. Bare minimum, print up a page off the net and have it in the garage with you so you don't forget.
I also just did this replacement a few weeks back on my 4.0L. Takes about an hour to get the gasket off and clean the valve cover up. Good time to check to see if your breathers (the venting hoses on front and back) are in good shape, or if maybe you need to replace some grommets.
