Modifying an Aircraft For SP2

I'm not completely sure if this goes here, or in the aircraft design boards, but if the mods feel that it needs to be moved, go ahead.... 
Anyway, I've been slowly going through some older FS9 aircraft and trying them out in FSX/SP2. Today, I tried the Fairchild C-123 K "Provider" located at http://www.simviation.com/fs2004military121.htm. I was surprised that there weren't as many compatibility issues as I guessed. The windows look ok, and didn't see any weird transparancy issues
The gauges included in it weren't compatible, so I switched them all to default gauges. I know the insrument panel isn't perfect, realistic, or finished, but it's still a work in progress.
The first thing I needed to do was invert the alpha channell for the Props. That took care of the solid grey disk, but the propeller itself still looks horrid. Is it possible to improve it?
Also, another issue is that at night, the exterior lights work, but there are no Instrument panel lights in the Virtual cockpit. I'm not too familiar with lighting in FSX, but I checked the aircraft.cfg file, and VC lights are in the light section, but I'm not sure what to do to fix it.
