I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.

In this case, kernel 3.3 has seen some very good power management enhancements that are not all found in the kernel 3.2. My question then is: Will this updates in 3.3 be somehow pulled into the 3.2 kernel used for Ubuntu 12.04?

If you are referring to the fix to the infamous ASPM power regression, according to this Phoronix article the fix has already been pulled into Precise. And looking at the changelog for the current Precise kernel, the patch "pci: Rework ASPM disable code" was pulled into Ubuntu's kernel at version 3.2.0-3.9. So yes :-)
