The spring pads are a question of personal taste. Changing the stock #5 pads to e-class #1's (5mm) will lower the front an extra inch and even out the wheel gap after you add the lowering springs. Our cars sit lower naturally in the back (even though it sits on stock #3 (9mm) pads, so the front appears to sit too high on the stock pads. I don't know why Mercedes did it this way, but the smaller spring pads make a dramatic visual difference without sacrificing a great deal of ride quality.
As for the tires, 265/35/19 is the closest diameter to the stock wheel/tire combination. Using a different size will likely change the accuracy of your speedometer. Besides, the bigger tires look dope.
