i need to replace the subframe mount bushings(or thats what i think they are called) whats the step?

You will need to jack up the car and support the body of the car. You will also need a jack under the sub frame. Loosen all 6 bolts. Remove three bolts on one side and lower the sub frame, replace the bushings, replace the three bolts and then do the same on the other side. Tighten all 6 back up and your done.
