I've finally found out the answer. It is possible, but fiddly.
For the source timecodes for every clip:
- Duplicate your sequence.
- Find the Timecode effects in the Effects panel and apply it to the first clip in the sequence.
- Double click the clip and go to Effects controls and make sure the Timecode Source effect is set to "Media".
- Then copy the first clip on the timeline.
- Select all video clips on the timeline and then Paste Attributes, just the Timecode is needed, untick everything else.
You will now see all the clips have the original source timecode and this can be compared to the original master clip.
To show the filenames of every clip on a given track:
- Add a transparent video layer.
- Add it to the timeline.
- Add the Clip Name effect to it.
- Double click on the transparent video clip and go to Effects controls and select under File Name - Display choose - FileName
and under Source track choose the track that the clips are on on the timeline.
- You may need to move this down a bit to avoid overlapping the timecode.
If you need to add filenames from another video track, just copy the Clip Name effect on your transparent video layer, and paste it below the existing effect, then adjust the position and size of each effect.
