Windows 7 How enable folder and file sharing on 2 W7 computers?

[Nisko]

I have a laptop running W7 Home Premium SP-1 and a Netbook running W7 Starter SP-1. They both belong to a Homegroup named 'HOMEGROUP1.' I would like to know how to enable each computer full access to all files and folders and printers on each other. If you can, please direct me to a step-by-step set of instructions (they might be different for the two versions of Windows 7 I'm using). Also, what is a Network Password? Thank you.
