How I download song from i tunes on my macbook and transfer to my iPod
I bought one song from iTunes and I can find it on my Macbook.
I want also to transfer the song to my iPod.

If you bought it on your Mac's iTunes then it should have downloaded into Music part of your Mac's iTunes library. If it's not there then did the purchase appear to go through successfully ? If it did then see if the Store > Check For Available Downloads menu option downloads it.
To sync it to your iPad, connect the iPad to your computer and select it in iTunes, and use its Music to select and sync it.
