I took a doula training course, and have doulaed at about 8-10 births, so it's a bit of a different scenerio, but here's my two cents....
We're not taking a course. I am an avid avid reader, and between that and my doula experience, there isn't anything pregnancy/birth mechanics that I could learn from a class. I suspect quite a few of the mamas on MDC are like that, simply because most of us find it so interesting, and have already done our research. DH is a paramedic, so he also knows the mechanics of it.
I took a childbirth course during my doula training, and it focused on pregnancy, the stages of labor, the physical side of it (what actually happens, dilation, etc) , breastfeeding and a small section on newborn care, and then yes, relaxation techniques. I left not feeling like I really learned much at all that I hadn't known already. We are looking into taking a three hour one on one massage class though- it's designed for birth by a prenatal/birth massage specialist, and she goes through and teaches you some positions, as well common massage technique.
But honestly, when it comes down to it, DH knows me very well when it comes to helping my calm down, relax, stay focused, etc. So instead we're focusing more on watching videos featuring natural births (that often aren't highlighted in classes), and then going through some more of the 'emergency type' knowledge.... since my best case scenario is an "oops UC at home".
I would research and try to come up with a plan for your pain coping though. Distraction and breathing might not work for you, but I would definately spend some time coming up with ideas for something that might. It will make you feel more settled I would think during labor.
