I was told the number 1 piston is at the back side of the motor closet to the passenger side.
Driver side, front piston.

Driver's side.
If they are the same as a 97 Maxima then you twist them, don't compress them. To compress the piston you do it with a 'Disk Brake Piston Tool'. You can get this at Pep Boys for $12. To compress the piston on the passenger side you turn the piston clockwise. To compress the piston on the driver side you turn the piston counter-clockwise. Be careful trying to turn the piston using pliers or some other tool as you may tear the rubber seal around the piston.
Piston crown is the top, skirt is the side below the ring lands (ring grooves). The as you say, the skirt often has cut aways to clear the counterwieghts on the crankshaft.
Driver side front.
I believe that you are talking about the piston.
If you double the area of the piston on the right side, it would create a force twice as large pushing down on that side. This would result in a greater pressure in the fluid, causing the piston on the left side to move upward with a force also twice as large as before.
the number one piston is on the left of you when facing the vehicle, it is the right side or passenger side and it must be at TDC for timing settings. (FENIX)
Dodge: front driver side.
