Sounds an awful lot like the ndiswrapper driver is broken in some way;
if you can't connect with (a) the command line tools from wireless-tools
and (b) you can't connect with wpa_supplicant, then NM's not going to
work.

First, I'd try to figure out the scan problem; from a terminal, do you
get scan results from "/sbin/iwlist <eth whatever> scan" consistently?
I also hear that ndiswrapper has better WEXT support now too.  Does
wpa_supplicant not work with the -Dwext option at all?
