Re: Going to 64bit
I asked a similar question a few months ago, and based on the responses that I got came to the conclusion that a "nuke and pave" would be the only way to be sure. I haven't done it yet, but I will likely install to a different drive and preserve my old install.
Someone recommended a web page for a marginally dodgy method for trying to pull this off, but I decided to just start over.
Now just to find the time to do it. :)

create your new installation with debootstrap. Crossgrading is not
supported, for instance installing the amd64 libc6 over the i386 one
will remove /lib/ld-linux.so.2.
32-bit programs continue to work if you install the ia32-libs package or

use an i386 chroot for them.
It will spare you the ugly ia32-libs package, but crossgrading is still

not possible. Yours truly attempted it, and dpkg refused to replace the
i386 libc-bin with the amd64 version¹.
