Replacing the coil itself is amazingly simple. Just unscrew the four bolts holding it down after disconnecting the wires. (Don't forget where they go) and swap in the new. There are a ton of threads about how to do the MSD swap and even that is simple, just costs more.
I ended up just going to the junk yard and snatching another coil from an EJ22E and grabbed a few minor things for both of my cars and it only cost me $12. I just bought the Speedyracer UEL Headers and the mortgage is due so no money in the budget to test out the Accel coil, hopefully some other time.
