now THAT's my kind of question....
For Holdsworth, check out his live album "All Night Wrong". That one's probably my favorite of his. Wardenclyffe tower, 16 men of tain, and hard hat area are also all good starting points. However, he does have a "best of" album out now, though i can't remember the title of it.
As far as Lane goes, Powers of Ten would probably be the most obvious one to reccomend. Powers of ten live is also really good and probably easier to find. The Tritone Fascination is really good too. As a whole, his stuff with Jonas Hellborg is the easiest to get ahold of, but I haven't listened to any of those albums in their entirety so I wouldn't know which of those to reccomend.
