The Outlook.com documentation contains an article to import contacts. The article also described how to import from Gmail.

Add Google Gmail contacts or contacts from a .csv

The smoothest way to use Gmail contacts in Outlook.com is to add them on the Outlook.com website.

You can also use the Outlook.com website to add contacts from a .csv file. (For Outlook.com accounts, using Outlook to import the .csv won’t work.)

See the article for full details.

There are also details about importing a calendar. Export it from Google Calendar and import it into Outlook.com.
