Cables are used to connect outputs and inputs to one another, so rather than taking the easy route to post here and hope someone will look up what you're supposed to look up and feed you with amazon links you should just read the manuals, see which plugs are used by the machines and then order the compatible cables.
As far as audio cables goes - I promise you you will hear no difference, especially if you're just starting to build your setup, so just go for the cheapest ones. For the interface connection you need a USB to thunderbolt adapter which seem unbelievably hard to come by, so good luck!
