No, and using windows 7 is not legal
Yes, you need to install Windows 7 onto Bootcamp (which comes free with the mac) or parallels, which you can buy. Then you can boot into Windows 7 or Mac OS X.
Windows software will not run on Mac. The Windows operating system will run on any Intel based Mac in dual-boot mode. You can use Boot Camp which is already installed on your Mac or another program such as Parallels.
Parallels isn't a place that sells Apple Mac computers. It simply allows an Apple Mac user the opportunity to purchase Windows operating systems for their Mac.
Parallels Desktop for Mac is a software package for Mac users to run Windows applications on their computers. This package is available from Amazon and many others

You can certainly move Windows to an external hard drive but Windows will not boot directly from an external drive. If you are running Windows in Parallels (See links below) you can have Parallels installed on the Mac's drive and then have your Windows virtual machine on the external drive.
Software is designed to work with a particular operating system. The Mac uses the Mac OS X operating system but you can also install the Windows operating system on a Mac. Windows is usually installed on a Mac by using Boot Camp (see the assistant in the Utilities folder) or with an emulator such as Parallels (See links below). With Windows installed the Mac can then use Windows software.
Parallels features true copy & paste and drag & drop - move files, folders and data seamlessly back and forth between Windows and Mac OS X.
It is possible to run Microsoft's Access on a MacBook Pro with Parallels Desktop. Parallels creates a virtual Windows computer on the Mac where you can run your Windows software. The Access database will need to be on the Windows side - either on the Parallels virtual disc or a connected Windows network as it will not be recognised if located on the Mac OS X hard disc.
Parallels Workstation for Windows? Use Sun's Virtualbox (information at http://www.virtualbox.org/). Parallels for Mac? Try Qemu, which may or may not work, due to its somewhat experimental status (OS X port at http://www.kju-app.org/).
The Logitech Dual Action pads only work on PC's, unfortunately. Consider getting Parallels for Mac so you can use Windows.
Unfortunetaly you can't. You can get a Windows setup on a Mac with Apples BootCamp drivers for a full native install or with an emulator like Parallels or VMWare that run in the background.
