Over the time I installed many i386 packages, which I no longer need. How can I clean up the system and stay only with the amd64 packages?

If they are not in your way, I would leave them where they are.
If you insist on deletion, use
dpkg -l | grep i386
to create a list of i386-packages. You can delete these after careful checking with something likesudo apt-get purge <package-name>
.
