If you are in help desk then you are probably dealing with mostly client issues, so starting off with the client exams should be a little easier for you. Then with the hands-on that you've got with Server 2012 maybe it will also help you with those exams. In the link above the Windows 8.1 book hasn't released yet but it's up to you to decide which OS you would like to learn. If you go with Windows 7 the Poulton book is highly recommended around here but I myself used the MS Press book. HTH
