Configuration > Settings is set to "Display URLs as www" for each site. ... If I type in the domain without the www it brings up the site up with the www, which looks right.
If you have set WMT to a preferred form, and you have a redirect in place for that same preferred form, then you are doing everything you need to do.
If it's working right, all Links to your site will be listed under your preferred sitename, with a "via this intermediate link" line for the ones that link to your other name. This is not especially helpful, but seems to be the way they do it.
