Pre-Publishing Checklist in relations to Instant TV Channel

Could someone please explain the various Pre-publishing Checklist items in relationship to a channel created using Instant TV Channel? I am currently working on a simple Non-Commercial Channel and will be adding a Commercial one afterwards. Some things seem pretty straight forward, however there are other things that are not very clear. At this time, I do not plan on doing any gaming channels.

I would like to thank everyone in advance for your help.
