Since your device is rooted, you can either use Titanium Backup to uninstall bloatware, or install Root explorer, mount as RW, navigate to /system/app and delete the .apk's manually from there.
Be aware that deleting certain system apps may damage your device. Also, Titanium Backup has caused many bootloops and soft-bricks when you batch-restore apps, so you may want to individually restore them instead.
