I wanted to direct your attention to the Prof. Emanuel Tov web site. It seems that he updated his page and now it has some of the very useful resources.
Among them is his collection of over 50 articles (available for free download) that constitute a very interesting read. And even though these articles do not relate directly to the Tabernacle, they still do provide some interesting insights on some of the verses of the books of Exodus and Numbers.
Other benefit of reading these articles, is that Prof. Tov. is working on the DSS (Dead Sea Scrolls), thus they provide some very interesting critical and comparative information.
Also, he is the author of the book called "Textual Criticism of the Hebrew Bible", which is not only an exceptionally well written, but also contains very extensive section on some of the verses related to the Tabernacle that are easy to understand even for an unprepared reader.
In fact, this book is almost completely available via Google Books for search and reading (click on the link above).
I hope that you will find this information interesting.
