"git clone" will create a new cloned repo. "git pull" will update the one you already have.
--no-edit just accepts the default commit message if you are merging other code in from a deviating branch. It is unnecessary if you are just pulling new commits from the same branch, but it won't hurt. Leave it in or take it out, as you will.
7-zip is a good unarchiver unlike the default windows unzip. You should be able to extract the tar.xz directly as a folder, play around with the options. (It's been a while, I usually use the linux command-line.)
The problem may be extracting to an external drive especially USB2.0 -- much slower to write than the internal hard drive. Even USB3.0 would do much better.
