Sven,
I have several questions regarding the master key or key use in general that so far I haven't been able to find answers in FAQ or man pages.
1. If I don't supply a master key or key file explicitly at luksFormat, will it be automatically generated? On Linux, is it generated by /dev/random?
2. If I use only key files (no passwords or phrases), will PBKDF be bypassed internally? Will the key file bits be used directly to encrypt and decrypt the master key?

No, the key supplied during luksFormat is the initial skot-0 key. The
masterkey is generated or can alternativly be supplied on the same command
line.
This is covered in the man page (as well as the FAQ AFAIK).
Quote from man page:
luksFormat <device> [<key file>]
Initializes a LUKS partition and sets the initial passphrase
(for key-slot 0), either via prompting or via <key file>.
