insulating shed

First up i'll say that the threads on this forum re: this topic have been very useful and i thought i had all my answers. But as usual i've over researched and have some additional questions. My shed is a 3 bay colourbond number and i'm up here on the central qld coast. It doesnt sound too hard, put some studs in the wall as required, line cavities with batts and clad it up. But then someone mentioned condensation...so my question is do i need to put anything between the colorbond and batts to stop condensation? Do i need to to leave a gap between the batts and the colorbond? Do i need to seal the batts off airtight from the outside air or do i need to leave some breathing gaps? And the roof, sounded like you take it off, safety mesh and sisilation and put the roof back on.. But the sisilation user guide says for it to work effectively you need an air gap. Does this refer to between the sis and the colourbond? If so how do you get this gap-just let it hang between the down between supports? i wouldn't mind putting aircon in either, will this cause condensation! All help appreciated and sorry for the poor paragraph structure, am typing this on my phone which makes it tough!

Here's some information that may be of help. Also have a look at this thread, post #420 on, a lot of good advice there.
