I don't know about PC Companion, but I use Titanium Backup to backup/restore all apps, as well as bluetooth pairings, saved WiFi connections, user dictionaries, etc. It also backs up contacts, sms, system settings, etc., but I rather use Super SMS Backup and Restore for handling SMS and Call Logs, Google Account for handing contacts, and hardly ever restore system settings, which I don't recommend unless you're updating to the same OS version, otherwise you might get errors.
I've been doing this for the past 4 years, and have the exact same data with me that has gone through 3 different phones, so I know it's 100% reliable.
