You can do it whatever way you want, though unless you are using K4PC to manage your collections, I find the easiest thing to do with my Amazon books is to choose to download them for my Kindle but transfer via USB.
That way it's just a case of loading them into Calibre, one button to convert, then I can take a back-up of my Calibre directory. Job done.
I personally then just transfer a dozen or so books from Calibre to my Kindle every now and then. Though if you find it a pain to side-load your books, immediately after loading them into Calibre, you can choose to re-download your books from Amazon but transfer wirelessly.
