The Debian amd64 port is as "pure" as possible. 32bit libraries are only installed in very few cases and mostly for non-free software (skype is for me the big culprit here). However, there is work in progress on true multiarch[1] support, where it will be possible to mix packages as needed. It *might* be ready until wheezy is released. [1] AFAIU other distros have bi-arch support, where some combinations of ports are possible.

Yes, at the moment it's so complicated to do a cross-grading that it's not worth it (I just wiped and reinstalled yesterday to move back from amd64 to i386).
