If you use traditional gas tube protector modules, they will pass DSL just fine. I've seen instances where the solid state ones don't.

You shouldn't use a ground rod. You need to bond the protector to the building's electrical ground connection or at least to the building's steel structure (if it exists). A separate ground rod MAY be driven, but since you still have to tie it to the electrical ground, you would be wasting your time driving one.
