Considering none of those files are hosted here I can't say much on them. In the LiteStep section of the Downloads page you can get the installer and the updated build. As for the theme though, you won't find it here. Too many ucky Apple lawsuits waiting in the wings I just don't have the time to deal with. But you can get some nice other themes here.

If you really are heart set on that theme try manually decompressing it to your themes folder and see if it will work. Some people package their themes in zip formats that don't adhere to the standard and can't be decompressed by outside apps 100% of the time.
