And unless you need to save $$ on the replacements, the safest, guaranteed fitment, best ones would be the OEM straight from dealer or OEM's from someone here selling them/parting out there cars.

C300
Unfortunately, the former... I bought a used 2010 with 100k miles... Had to get new rotors and pads but when they were trying to get the calipers back in, they got stuck and after a few times they were able to get it down... but now i hear this grinding sound coming from the front and my gas mileage is about 10-15 mpg combined.... I think its because the brakes are constantly engaging...

Your issue may be resolved by simply removing the caliper and re-seating the pads.
The pistons do not rub on anything. They push on the inboard pad to provide the stopping friction. You say your MPG has gone way down, so it does sound like the brakes are being constantly applied, but that shouldn't be causing a grinding noise.
Also, is the noise only coming from one side, i.e. you worst case you wouldn't need to replace both calipers?
