PowerPC-Migration

I recently upgraded to Lion (new MM server). I have a couple of important apps, which originally ran under PowerPC, but had been updated to support Intel natively.
The only problem is, that the original installer CDs include packages, which only run under PowerPC. There seem to be no available full Intel versions, but the updates.
Apple Customer Service told me, that I couldn't just restore from a backup on my Time Machine, since that would crash my system. I did it anyway and ended up losing the server apps and a couple more. The system became unstable.
Then I thought, I could copy all the necessary files manually from my old 10.6. OS. However, I do not know which exactly.
So my question is, whether there is an app, which tells me, where all the files of an installed program are located. A install-package-analyzer of some sort?

Any hint to resolve this issue is appreciated. Thanks!
