Yes and yes.

WPA-None is not defined by IEEE standard (it is from WPA specification)
and it does not match with the RSN mechanism you are describing here.

wpa_supplicant does not support 4-way handshake in IBSS case (or well,
there is some experimental code to do this in the current development
branch, but it not yet complete and would require driver support for RSN
in IBSS, too).
