I've had alot of experience with modifying and repairing laptop lcd screens. I can tell you now that you will have no luck find VGA pinouts for your raw lcd screen because they simply aren't there.
A laptop lcd screen does not operate without the integrated controller on the laptop motherboard. With most modern laptops this is an LVDA interface but on older models with passive matrix the controller is often completely proprietary, so you can forget about using old laptops. In the case of the LVDA based screens, you are looking at about $500 for a standalone controller with a VGA input.
So basically, if you wanted to go ahead with this mod you would have to either find a laptop with a suitable input (VGA, composite, whatever) and keep the laptop running as is so the screen can use the onboard controller, or try and find a working combintion of raw LCD screen and standalone controller. With the first option, the mod pretty much becomes impossible because you can;t replace the guts of the laptop.
Sorry to rain on the parade, but I've been where you are now, trying to make a standalone screen out of recovered laptops and have found that it will always cost more than just buying a desktop LCD monitor.
