Really Drupal tips. (Rich: turned into an Agony Aunt session!)
Theming the same content type differently in different locations is hard. But Display Suite is a replacement to Panels that can help.

Node Composite alternative to Panels. Easy to use.
Rich: Display suite + context nicer than Panels? Definitely need to try that!
