What is a PFX file?

The PFX is the certificate you want to use to sign your binaries. Signing them ensures other people that it's the original file released by you/your company and proves that no-one has tampered with it.
But remember kids! No security is strong enough ;-)

Do I need a timestamp server?

Nope, but it you can use one when it is provided by your certificate authority.
