Question 1:

a) The project is mainly Z1 HDV 50i footage
b) The project is being rendered to Lagarith for HD archival
c) What colour space should be selected for optimal quality lossless renders with minimum colour conversion?

The options are:

YV12
YUY2
RGB
RGBA

e) Does operating in 8bit or 32bit mode make any difference to the ideal colour space selection?

Question 2 to come later... :)

Cheers!
