Circular package references are allowed.

No.

In both cases, getting it to work may be a little tricky. In particular,
imports of the form 'from module import xyzzy' should be avoided
in these cases; use 'import module' instead.

No. The global keyword is used to allow assignment to module level
variables in a function. By default all variables assigned to in a
function are local variables.
