I used DownloadThemAll - A Firefox add-on/download manager - to download it. Had it down at ten parts, and it took maybe a minute or two to download. I'm doing it again just now to test the speeds, and I'm going between 300 some KB/s, to 7-800 KB/s, and hitting, fairly often, just under 1 MB/s (about .98)
You don't need to extract anything. Just download the ISO.
