Bad signs in a department for PhD
I agree that this is generally a bad sign, especially your number 2, but I would add a "but" to this answer.

When the language used for teaching at the University is not English, situation number 1 can arise. Some department have a hard time recruiting and keeping researchers that are willing to learn a second language and teach in it.

Another way to evaluate the quality of the department would be to look at the collaboration they have with other institutions and the scientific literature they produce (among other things).
