How to set up QGIS print composer options from the python console?

If I have a print composer called "ABC", I would like to "tell" its composer that I would like to

1. update "Map 0" to simulate the "set to map canvas extent" button activation


2. update certain text labels


3. activate "export to image"

Thank you.

On the topic of print output from pyQGIS: http://www.qgis.org/pyqgis-cookbook/composer.html (Note: master has QgsComposition::loadFromTemplate method, which 1.8 has not).

Basically, in 1.8, you have to create the composition (with map, labels, etc.) from scratch in code anyway. So no updates are needed.
