If its of any use, I have built a Maloof style chair using the Hal Taylor plans/manual. In a nutshell, they worked together well enough to allow me to produce a chair I am rather chuffed with. The manual is not the greatest with regard to clarity or accuracy of labels, but a thorough reading should suffice. A particular irritation is a constant reference to 'thickness' or 'width' but without any plans or figures to specify where this width or thickness applies to on the specific part in question. There are no 'plans' as such either, but a set of full size templates on paper are quite sufficient. Hal is, however, very good at helping out via email on any issues you may have.
Cheers,
Adam
