I searched around a lot and here's what I did.
download this file from apple to export your address book as a .csv
Apple - Downloads - Productivity Tools - Export Address Book
once you've exported all contacts, go to http://www.google.com/contacts and click "import" in the top right, then just selct the csv file and upload it.
I know you can sync with address book by exporting your address book contacts and then importing them into the gmail account you had to start with the Droid. This works reasonably well and you can clean up any confusion within the gmail account pretty easily.
I'm still trying to figure out ical and itunes.
