Hi,
usually I would say just use WinUAE:
http://www.winuae.net/
It is just the emulator program itself, though.
To fully emulate an Amiga, you also need an image of both the KickROM and the Workbench-Disk-Set (ok, these are like 5 disks for Workbench 3.1
).
PM me if you need help or more details regarding these.
If you are looking for an all-in-one package you might consider the commercial AmigaForever with some nice bonuses:

Technically, Amiga Forever is based on WinUAE and adds some nice GUI and other stuff such as aforementioned images of KickROMs and Workbench disks as well as other commercial stuff. And nice videos
.
There are various tutorials out there how to set up an emulated Amiga with WinUAE.
You might start here:

Once you have the system set up and running, just check back here and let us know.
From there it is only a few clicks to access the data.
