MySQL 5.6 replication

Hi, I need two things. I have MySQL 5.5 and I want to have it upgraded to 5.6. This download is not available in the standard Debian repositories. And two, I want to have these two replicated for a failover situation. Also, when the master server is back online, the newest modifications on the slave server should be replicated back (if this is possbile). That's it! I think it's very easy for someone who has done this before, but I don't have the time to find a good tutorial. I have seen some but mostly for Debian Squeeze and MySQL 5 and not MySQL 5.5+ Thanks
