Reset Finder Prefs?

I'm having some issues that suggest I need to reset Finder Prefs. I believe this resolved similar issues awhile back, but I don't recall exactly.

What settings get lost (returned to default) when Finder Prefs are reset? I prefer to know in advance.

With Adobe Photoshop, many application settings revert to default after prefs reset, and it's possible to make permanent errors as these minor settings are scattered throughout the interface.

Thanks.
