You can move (copy, port) your user profile. Concerning templates and scripts there are contained folders whose contents you may delete in advance of the moving if you don't want to pass them along. Also the backup folder should probably not be included.
Concerning the location of your user profile see this wiki.
It's different with the software itself. A standard install with settings on the level of the Operating System must be done anew on a different machine. On Win e.g, you easily get the file associations you may want.
Again on Windows (and most likely on Linux having 'Wine') you can also use an extracted PortableApps package (there are also different brands probably) of LibO which has its user profile in its specific place. Such a LibO you can take with you on a USB stick e.g, settings, templates, scripts and all. File associations are, of course, not offered by default by portable software. On a specific computer you can arrange for them manually. Depending on the medium loading/saving speed may be reduced.
