R3 and R186 will be resistors. C7 and C8 are capacitors.
The solder seems to have run from the larger capacitor to the smaller capacitor and resistor, this could be what has blown the resistor. Some PCB resistors have the rating stamped on them, so you could actually replace but it looks like these don't.
Not sure what RA9 would be, but that doesn't look so damaged.
