I'm not sure what your question is. Are you asking if contacts are synced with facebook on the actual android handset?
If so, yes...mine are synced. I made no changes to my account settings within facebook.
Been using it for more than 24 hours now and push notifications seem to be working fine. It does not seem to notify me on my phone if a new chat message is sent. I suppose you would have to have the app actually open and running in the BG to get those. Private messages and notifications are being pushed without issue so far.
