Hi there Little Ern,
I've worked with cameras that restart their file numbers at 0 a number of times in the past, it's a pain!
While I'm not a video expert and somebody else out there may have a better workflow for this, what I have always done is a batch rename of the files with Adobe Bridge as soon as I transfer them onto my computer... or even with your computer's Explorer or Finder window (depending on how important file information and timecode is to you, if seen some weird glitches when renaming directly in my browser!)
Once you've renamed your raw clips, you can re-import them with the new names and you are good to go.
Here's a link to another thread discussing similar issues.
There is somebody towards the end of that conversation that mentions renaming your clips in Premiere and using the Project Manager function to copy your clips (and all associated metadata) under the new names to a different location. You would then be able to use these new clips (with appropriate names) in your main project.
So you open a new project, import your clips, change your clip names and add whatever metadata you want, go to File-Project Manager, select the location you want to get your files from and let it run. You then import the new clips in your project and Bob's your Uncle.
