You should be able to do this with a basic set of hand tools (ratchet/socket set). I don't know what it involves to get any covers off (may require some torx sockets or drivers to remove, though is probably only connected by some 10mm bolts or fasteners). The coil itself is a "coil-on" configuration which, in and of itself, does not require any tools to remove. You flip the small piece which holds the wires in place (easily seen on a replacement coil), detach the wire connector, pull on the coil while giving it a little twist and it should pull right out. Replace it with the new one and you should be golden. Put a small amount of dielectric grease inside the boot side (which connects to the spark plug) of the new coil before installation. This will help it from sticking when you want to replace the spark plugs. If you are changing more than one coil, do it one at a time. It really shouldn't be hard to do. Just keep track of your parts you pull off (engine cover, bolts, etc).
I found what appears to be good instructions here (though it shows a 6-cyl model) and a video of an older model where the guy is replacing the spark plugs. This may be useful for removal of any engine covers. Hope this helps.
