Need Help Setting Up QoS on RT-68U

Need help setting up QoS on my 68U router running Merlin's Fork firmware (v14.1). I've never set up QoS before, so any help is greatly appreciated.

I need to prioritize an IPTV box, my iPad (Facetime and Netflix) followed by general web browsing. I have a 60/5 speed through my internet service.

Under "Traffic Manager", my settings are the following:

QoS: on (AUTOMATIC MODE)
Upload Bandwidth: 5 Mb/s
Download Bandwidth: 60 Mb/s
Default Priority Level: Low (default)

Is the above correct...
