I am familiar with the basics of SPF but I am having trouble determining exactly what I need for my setup.

I have my email done through Google Apps to send and receive email for my domain, example.com. Now I am adding Mailchimp Mandrill as a valid outgoing SMTP server for the same domain. I currently dont have an SPF record set up for Gmail.

When creating the SPF record for spf.mandrillapp.com, do I need to include gmail.com also? Or example.com? Or all three? Or only Mandrill?

Yes, you should include Google's SPF include for this domain, even if no SPF record was set up previously.

Your record for example.com will probably look something like:

v=spf1 include:_spf.google.com include:spf.mandrillapp.com ~all

when all is said and done.

You don't need anything additional for example.com unless you are sending email directly (e.g. with Postfix or Sendmail) from another server.
