I like to keep non-system stuff on a separate partition, so I have /home and another partition, /pub that I use. Personal stuff, I organize in /home/<user>.
I keep downloaded stuff in /pub/download with separate folders for tars, bins, rpms, etc.
I usually extract stuff to some temp folder as I toss it after compiling and installing it.
Of course, kernel-source or other source code that needs the tree, I extract to /usr/src or usr/local/src, depending upon what it is.
I recommend something like /home/<user>/documents for notes and umportant stuff you have written.
