downloading Patches from MirrorsFollow

I just picked up another copy of WoW for myself, to install onto my laptop, however, the blizzard downloader is not working for me, and I have resorted to using a mirror, the question is however, where should I download the files to, and how do I do it specifically?


Also, the estimated time for it to download (from filefront.com) is around 3 hours (this is for patch 1.12), does this mean that I will still have to go through the blizzard downloader and the installation of the patch as well?
