Here are two links for you. The first is for the SYW, but things were much the same. The second has the detailed OOB for Mollwitz Chotusitz and Soor.

There is a tendency for gamers to go for the 'three battalion regiment' for Austrians but this is a bit of a misnomer. As far as I can gather, they generally deployed as two battalion regiments. Where three battalions are present the third often comes from another, badly depleted, regiment that has been folded in for admin purposes, temporarily losing its own regimental designation. I can't remember where I read that.
Of course, this period also predates any form of standardised brigade or higher formation. The army building block is the regiment of infantry (generally two battalions) or cavalry (generally in five squadrons). After that, units were brigaded together (usually as one arm brigades) as the C-in-C deemed fit for the occasion.
There are a couple of Duffy titles that would help you. I'm glad I got mine a long time ago because, blimey, they are pricey these days!
