Whitelists add their own problems:
1. What stops a spammer impersonating someone on the whitelist by faking the
headers?
2. How do new non-spammers who genuinely want to contact you get onto the
list?
3. What happens when people on the whitelist change their email address?

And what percentage of spam fits this category? (Make sure that your own
address is not on the whitelist, that IS commonly used by spammers)

Good point. Especially difficult if they are unaware of you whitelist
system and just assume that you would have received the message.

Hopefully they send you a message before the change advising about the
impending change. If not then it may take a few messages before they
realise that you are not receiving them.

How will the know who is on the list ?

Phone, fax, snail mail, web based form fill in page

They should let everyone know beforehand or have an overlap period to
catch the few they did not inform.

Not the message is bounced back to them with a note to contact you via
another means (snail mail, phone NOT fax as there are now fax spammers
too), or a secure web form fill in, ie they have a URL which is valid
for 7 days 1 off use so that they can put in a quick message with who
they are in real life and then then email address, this will be sent to
the white list owner who can choose to add/or not the person.
