transferring old pc outlook emails to mac

Hello. I am the proud owner of a new old Mac. I've had years of pain on PC's and hope to find some peace in mac world........

Anyway I'm sure it's a common question but i cant find info on how to transfer my many old emails from my old PC.

I'm using Outlook 2003 on PC laptop and have 10.8.3 Mountain LION INSTALLED ON MY 2011 IMAC AND AM USING MAIL.

I would think that I just need to drag the Inbox and Sent folder from Outlook to a shared file and then set up a network between the mac an pc and drag files across and then go File> Import Mailboxes and import them across (read that somewhere)?
