Do I need a new electrical panel?

The panel is Siemens G4040B1200, which came out in 2009 I believe. The house was built in 2002. There was a ground fault last week where the hot wire touched a side panel of AC condenser and that fried lot of things, even stuff on a separate panel from the condenser.

Looking at the wiring, it looks like the earth ground (bottom left) in both panels should be near the main breaker up top, no?

I am also considering a whole house surge protector like this one QSPD2A065P for unrelated reason than the ground fault event. Any thoughts on that would be appreciated also since it looks like there’s no L-G protection unless the panel is bonded, which i believe is the case for my panel, correct?
