The main difference between the Workbook and the Proceedings is the final page size available, which is approx. A5 in the case of the Workbook and almost A4 in the case of the Proceedings. As far as the Workbook is concerned, it is completely up to you what you put in the pages, whether you use two columns or a single column format; the only thing which will be enforced is the final size of the text mirror (your camera-ready contribution will be reduced in size to fit in) which is approx. 12.3 cm x 17.2 cm (4.875"x6.75") and the number of pages (in 95 per cent of cases, four pages). If you follow the Workbook instructions of the Web page, the final font size will be 9pt, i.e., still readable without a magnifying glass. The latex file available on the web page is by no means an official "latex style of the Workbook", it may just serve for a guidance about one possible way, how to create a properly formatted document. (Users of the old LaTeX 2.09 may use an analogous document.)
In fact, you should create two different documents, describing identical physics: one that fits the Workbook and (if you wish to submit) another one that fits the Proceedings. If you manage to fulfill both tasks with a single document formatted in two different ways (probably not), great, but it is up to you.
