Question about channels and functions

So I’m considering cutting the cable, but I’m wanting to verify channel availability and some things.

So me and my wife have checked, and we only watch a total of 16 channels and some are seasonal for just a single show. Between her, our son, and myself channels we watch are.

Mine
FOX –
NBC –
CW –
USA –

Hers
ABC –
E! –
Lifetime –
Bravo –
Hallmark –
Lifetime –
MTV –

Our Son
Nickelodeon –
CartoonNetwork –
BabyFirst –
Sprout –
DisneyXD –

First question is. Can some of you experienced users tell me which of these are available, and which are not. Just put a (Y or N) next to the channel.

Second question is. Do the channels show current live TV, or save the most current NEW episode that was aired just in the last few days for access any time? And if tthey are LIVE only, is there some sort of DVR function available?

Third question is. What am I looking at as for cost for the channels that are available?

Thank You in advance!
