Thanks for the report.
I will get the WPA/WAP thing fixed.
I'm afraid you'll have to setup your wireless after installation in cases like yours.
The installer is not designed to scan for access points, just scans your hardware. if you can provide an ESSID, it will configure the interface, otherwise, use wicd to do it.
On a side note, B2 has been release, the change you request for the LILO screen has been done, and there have been more inprovements in the lilo department.
You should try B2
