At least some of the formats you mentioned are not available on Windows unless uniconvertor is installed. This is now included by default in the 0.47 development branch. To download a copy, go to http://inkscape.modevia.com and look in the Win32 folder. There are also daily builds for Ubuntu available at http://launchpad.net/~inkscape-nightly/+archive
I believe that WMF used to be unavailable on Linux because it is primarily a Windows format - not sure about the current status of that format.
I would suggest that you develop your manual with version 0.47 in mind. You will probably find that 0.47 is closer across platforms.
