Have a look through the macros on this site.
The fancy auto white balance, you can just use colormatch, there might be one or two more clicks involved.
For the instancing thing, shake has had hat for a while, just copy and use paste linked instead of paste. then if you want to de-link something, just change it, although thanks to shake's concatenation, it might be better to just add another node.
Shake is all about giving you the building blocks rather than packaged effects.
