Question

how to setup ipad home sharing. i cant find the button.

Answer 1

Home sharing allows you to stream your computer's iTunes library to your other computers/devices, so for that to work then yes, your PC will need to be switched on and have iTunes open on it - your other devices and computers, which will need to bo connected to the same wifi network as that PC, will be able to stream your music, films, TV programmes from that PC.
The cloud is separate. Based on your username I'm assuming that you are in the US, so you would be able to redownload your iTunes purchased music, films (though not all studios allow redownloading) and TV programmes from the store directly on your other devices (though you could also sync them from your PC) - so they would then be stored on those devices, as opposed to being streamed from your PC. But redownloading is only possible whilst the item remains in your country's store, content providers occasionally remove things, so it shouldn't be relied upon.
To be able to upload your own music (e.g. music copied from CDs or bought from other sites) to the cloud you would need to subscribe to iTunes Match, which is $24.99 per annum : http://www.apple.com/itunes/itunes-match/
