Secondly I have looked at Stellarium to find the position where Venus will enter the sun as viewed from Brisbane as our school kids will be imaging this and I would like to know where to point the c8 so we can capture this.

To answer your first question the mean distance for AU is 149,597,870.700 kilometres or 92,955,807.2730 miles. (give or take a few centimetres/inches) I understand that measurement was done in Kilometres.
