You can get the mint xfce stuff as soon as they're available by installing packages (e.g. mint-meta-xfce, thunar-custom-actions-xfce, mintupload-xfce) from the repositories. However, according to http://packages.linuxmint.com/#7main
there are non yet available, so I'm afraid you have to wait.
Alternatively, you could try adding the felicia repos, then installing mint-meta-xfce, but you will almost certainly have undescribeable problems with that, as there will probably be conflicts.
If you have a question that has been answered and solved, then please edit your original post and put a [SOLVED] at the end of your subject header
