1. There are some re-settable whole-house protectors but that depends on how they have been hit. Some surges are simply destructive.
2. Another surge protector at your system (the source, btw, is your breaker box) will not defeat but supplement the one in the panel. It will provide additional protection for induced surges which do not enter via the panel and will usually have a lower cutoff voltage.
3. Your panel should already be adequately grounded or it will not meet code specs.
4. I use the JPS Power AC In-Wall cable.
