I'm creating a decimal installer (for Py2.3 users), making tarball, .rpm and .exe versions available.

What I don't know is what to put about license and copyright.

In the language of the PSF license, you're making "a derivative work" then. Your derivative work is your work, and you can license it however you like (although, as the PSF license says, you must include the PSF license and copyright notice). The copyright is yours, since it's your work.

Regarding copyright, my first draft says:

Copyright (c) 2004 Python Software Foundation. All rights reserved.

You hold copyright whether you say so or not. You won't get into trouble by claiming the PSF holds copyright, though.

Regarding license, didn't put nothing yet, should I write something like the following and include the file?

No matter what else you do, you must include the PSF license and copyright. The license you want to use for your part of the work is entirely up to you; the PSF license imposes no restrictions there.

See the file "LICENSE" for information on the history of this software, terms & conditions for usage, and a DISCLAIMER OF ALL WARRANTIES.

That would be suitable if you want to leave the impression that you're licensing your work under the terms of the PSF license. That's fine, if that's what you want to do. If you want to write a license saying people have to pay you a million dollars each time they use your installer, that's also fine.

Remember that the "decimal installer" will be available for download not in a Python location.

That part doesn't really matter. What you suggest above is all fine.
