That'* about it IF you have an impact wrench for the crank pulley (HB) bolt.
If not, you will need to pull off the flex plate cover and jam the plate against the block. I use a big phillips head screwdriver through one of the holes in the flex plate and turn the crank bolt CCW until it jams the screwdriver shaft against the block. This will hold the crank to remove the bolt with a socket, breaker bar and long cheater.
Once the pulley bolt is out you will need three puller bolts that will probably not come with the puller kit. These are 6mm diameter x 1.0mm/thread x 70 or 80mm length. The holes are kind of hidden on the HB, but they are there. You will also need hardened flat washers to fit the bolts outside the slot on the puller.
Once the HB is off, there is a plastic cover over the CPS that pulls off pins. Under that is the CPS attached with one or two 10mm head bolts.
$275?? I'll do it for you for $250!
