Is anyone here a bit of a wiz with cPanel/WHM?

Basically I bought a dedicated server with a whole heap of space and I want to move some clients onto the server, now I have paid people in the past to do this as part of a package but now I am going it alone I ain't got a friggin scooby.

I have 5ip's and can get more as and when I need them, but I need to create a separate account for each of the websites I host, the first one to move is my sisters, so can anyone give me a step by step guide on the creation of the account through to how I get her domain name to point at the account? I know it may be alot of work to tell me but I would really appreciate it.

I have read the user guide but its like omg thick and confusing
