Sounds to me like primarily you are looking for more behind the scenes studio model references as opposed to the ones that talk about the guts of the ships. As such, the choices are a little limited.
Star Trek Mechanics 4 (the Japanese publication) is probably the best reference overall specifically for studio models. It has a little coverage of TOS as there weren't too many behind the scenes shots taken of the studio models. But, it does have some good pictures of the TOS Enterprise built for the DS9 episode "Trials and Tribbilations" in it. There is also some coverage of the TOS Klingon ship as well. The best benefit you get is the shots of the studio models built for the more recent TV shows and some of the movies. There are some rare studio model shots in here.
Back issues of the out of print "Star Trek: The Magazine" have periodically featured images of studio models, although I don't know of an online source for a description of the contents of all the issues. Rick Sternbach did a very nice featurette on the Voyager studio model in one issue with never before published photos. The magazine does tend to be a little more fluff than hard data for modelers though, although each issue usually included 5 view drawings and some of them were of very rare ships typically only visible in background shots or debris fields (such as Borg battle aftermaths). I wish the magazine was still out, but I can see why it is no longer in print as after awhile it became a bit of a rehash.
"The Art of Star Trek" by Judith and Garfield Reeves-Stevens is a good behind the scenes hardcover book with images of stage props and set design. There are some images of studio models, but not many.
"ST:TNG: The Continuing Mission, A Tenth Anniversary Tribute" is a trade paperback covering the behind the scenes production of all seven seasons of TNG. There are some pictures of rare studio models in that, but not much. Still, it is nice to glance at periodically.
The biggest problem with TOS references is to this point, there has never been one studio model related reference ever done in print form. Nobody ever really set out to document things from day one like Star Wars since they were primarily involved with keeping the show in production. So you have to pull a little from here, some from there and then some. The Mechanics book is about as close as it has gotten and their lack of information on some things shows just how tough it can be to find this stuff. I wish the IDIC page was still around as that website had your best one stop shop reference for all things Trek, especially TOS. Some of that stuff is archived, but I don't quite know where to find it.
My advice though is you can probably find the harder to find images online through sites such as this one as opposed to the books, given that the web has allowed for the publication of a lot of previously unreleased material. The Mechanics 4 book would be the primary one to get if you can find a copy (hard as it has been out of print for a few years) and I wouldn't worry about the other two unless you can find them for an inexpensive price at a used book seller.
