As for anchor text I link to use the domain name. e.g. the clickable text would be 'example.com'. It's not always possible to do that but when it can be done I think it should be because it leaves no doubt that you want to link to that domain and it leaves no doubt as to where a visitor will end up if they click.
Interestingly, there's been post-Penguin debate about the possibility that Google considers it spammy when a site has a lot of inbounds that are just the domain name for anchor text.
