You're probably looking for ADF images of the Workbench disks. You can find them on the Internet Archive and The Old Computer if you do a web search.
If you have a CF adapter for your PC, then you can use the CF card as an Amiga hard drive inside WinUAE. It's the quickest and most convenient way of installing everything you need.
