I'm sorry to take a while to reply to this.
The W8 apps contain the contacts and calendar(s) at Outlook.com. With calendar you can subscribe to a different calendar eg Google (in my case I have iCloud). Then with the calendar app open and using its settings you can choose which calendars to view or hide. In your case I would just use Google calendar. The snag is that is doesn't sync between the calendars however you can drag and drop items between them. Hence my suggestion just to view Google calendar. See Option 2 in the answer here Answers Microsoft
Contacts are more difficult and I haven't found a satisfactory way to sync contacts.
