OK, I just completed a 'down-conversion' from the HD file (AVCHD/.m2ts) recorded with my CX150 on the highest setting to the SD file (.avi). It's very simple in Sony Vegas and I am sure this is just one of the ways you can attempt to do it.
After loading the HD file(s) onto a timeline and performing any edits you desire (adding transitions, music, etc) you can chose "Project" and then "Render As". In the dialog box that opens you specify the type of file (.avi) and choose a template (for SD format NTSC DV Widescreen). And that's all really. I rendered about 1 minute 30 sec video (original size was about 240 MB). The SD video in .avi was about 326 MB. I am not quite sure why the resulting file was larger but that size corresponds to the 12 GB per 60 minutes of recording I get from my old SD camcorder and miniDV tapes I have.
I am therefore confident that recoding in HD and down-converting to SD only as needed is your best option.
One tip I can offer when working with Vegas that was not immediately known to me: make sure to match the project properties to the files you will be working with. For your source HD files you should click on "Project" and then "Properties' and select the HD from the available templates.
