Yes you will lose quality if you try and edit in a editor that is not designed to edit mpeg2. The reason for this is that the editor converts the footage to its own format, then converts it back to mpeg2 when you save. If you try and convert to another format like dv avi you will also lose quality. A specialised mpeg2 editor like Womble mpeg wizard or VideoReDo do very little re-encoding of the mpeg2 file when saving, and so are the best for editing mpeg2 video.
A good test to see if your editor is re-encoding the mpeg2 file is to import it into the editor and then without doing any editing, saving it again as a mpeg2 file under a different name. Then compare the 2 file sizes. If the 2nd file is smaller than the 1st, you have lost quality.
Another good reason to keep the file in mpeg2 format is that if you want to burn a DVD, you don't have to re-encode it, it's already in the right format.
