The actually installation of the CPU chip is almost idiot proof. Just drop the CPU on the MB (check of course the orientation), and turn the tightening lever. I usually check where the MB pins hit the CPU contacts, and re-insert the CPU so that all pins hit the CPU contacts as close as possible to the center of each contact (so no pins are on the edges, and possibly have a chance to move and get no contact). There's like 0.1mm playroom to move the CPU chip towards each corner, so I move it to the best corner and then turn the tightener lever again.
The current Intel CPU fan is very easy to plug in on the MB. It has 4 black plastic screws on each corner, which you leave in "up" (and max counter clock-wise rotated) position and just push them with your fingers trough the MB holes. Then you use a flat screwdriver and turn the plastic screws 90 degrees clock-wise (like any screws to lock). After you have turned them 90 deg, they should be really tight, you can test their firmness by pulling the CPU fan up with some force, the rig should not lift an millimeter from the MB.
