What it the easiest way to Emulate OS 8 or 9 with a PPC ROM on Windows Vista?

Secondly where can I get the ROM's from? I have Quadra ROM's but want PPC ROM's.

Thirdly I have all kinds of MacOS CD's from 7.5.3 to 9.2.2 so that shouldn't be a problem should it?

Thanks in advance.

EDIT:

I am also looking to emulate a IIgs or so. Nostalgia has taken hold.

BTW is there a USB 5.25" floppy drive?
