I've found plenty of entry layouts...but I can't seem to find the frontpage (or is it "my diary?") layouts...can someone help me out please?

You can find a bunch of frontpage layouts Here.
in the entries list every title that has [set] next to it means there's a frontpage layout as well as an entry layout. =]

Thank you! :)

Classic Layouts has a ton, too. :)

thank you! :)
