Thanks, Aiji! :-)

1) Sticky headers
This is rather old and somewhat buggy code. It behaves incorrectly in mobile mode. As a workaround you may want switch your browser to desktop mode ("Desktop site", "View desktop site", "Request Desktop Website", etc. option). I think I will solve the sticky headers problem someday. :-)

2) Translated and Translations
As far I remember, 'Translated' means 'total number of sentences you added as a translation, percentage of original sentences belonging to natives, percentage of your sentences having a translation'.
'Translations' means exactly as you stated.

3) Links in the Contributors chart
Links is Tatoeba is created in pairs. When you link your own sentence to some other sentence the corresponding link from latter to your own sentence will be created automatically. So you are right. :-)
