HCM install questions from a SAP newbie

I have been given the task of installing a new SAP ERP system for development use, but have not been given training on how to do it. I have run through the install starting with the SAP Solution Manager installation master DVD successfully and been able to login and see transactions that I am familiar with (SU01 and others) what I do not see is the HR transactions PA40. I have been reading and think that I need to install HCM but in the software I recieved I don't see a DVD for HCM. Is it part of one of the other pieces that I have?

Any point in the right direction is appreciated.
