Welcome! :) Do you plan to also use Office2013 and/or SkyDrive to sync your Surface Pro with your Android and vice versa? If yes I'd love to hear how an Android plays along with W8. But even if you don't, feel welcome :)
Just moved my work files from Google Drive to Skydrive so that's how I'll sync my files (just can't edit my Google phone or tablet). So far using Windows 8 PC all my contacts and Gmail have syned without any issues so I'm assuming on the Surface Pro It'll be the same. Haven't run into any issues yet just wish I could sync my Google Maps and all my saved location within the application other then that they play along great.
Welcome aboard. I have the Surface RT and love it. The Pro should be even better. Hope you enjoy it and let us know how it's working for you. There should be some helpful threads with tips and information sharing the Surface Pro forum once people get their hands on them.
