Need some help checking my order

[darkknight302]

I'm not sure if I order the right stuff. Can someone double check if they are the right ones.
Front Brembo, they came in different boxes, so I'm confused.

The front left says prime, while the right is normal. The left also has dark print and the right doesn't.

For the back, I'm assuming they are the same regardless if it's left or right? I order 2 since it didn't state that it was either left or right like the fronts.

For the pads, I'm assuming one order is for both backs and fronts? I opened it up and there's 4 pads in one order. Should I send back the extra pads?

Wear sensors, I order 2 of each because I'm assuming all four pad gets them but reading online only 2 gets them?

rear rotors internal fins aren’t directional so doesn’t matter what side, front you position them by fin direction.

Wear sensors are front left and right rear. One each on the inside brake pad. Total of two sensors.

Pads are two pads each side. So four pads total front, four pads total rear.
