I assume what you mean by "device manager" is the system by which you access external hard drives, flash drives, printers and so on. All file systems (drives) show up on the desktop when they are plugged in. To see what printers are attached to your computer, go under system preferences and look at Print & Fax. Things on the mac are plug and play, so if you are having any trouble with this you need to be more specific about what you need help with.
Goto Device Manager on Windows if you have a Mac goto the apple logo at the top left hand corner and click about this Mac then go into more info.
Blackberry software for the Mac can be downloaded (See links below) if not included with the device.
Run the application Photobooth (in the applications folder) if you can see yourself there is a camera built into your Mac (all the recent versions of the Mac will have a camera). if you cannot see yourself, or you do not have Photobooth, then you do not have a built in camera but you may have an external camera which will be obvious and will need to be plugged into your Mac for it to work.
Can't unless you have a Mac or Apple device

Microsoft Office 2008 for Mac is created by Microsoft for Apple's Mac computers and it requires Mac OS X to work. A Dell is not an Apple Mac and is not running Mac OS X and so Office 2008 for Mac will not work.
An apple ID can be accessed on any apple approved software of device. It can be accessed on itunes on your computer/mac/laptop etc or your idevice-e.g ipad ipod, iphone etc.
