No, the iPad has no cursor, so the mouse wouldn't do anything. You can connect Bluetooth controllers such as keyboards and game controllers.
There are some tablets that do allow a mouse to be used such as the Android tablet. You cannot use a mouse with an iPad unless it is jailbroken which will void your warranty. You can however use a bluetooth keyboard.

As the standard iPad uses a touch sensitive screen as a control surface and does not have on screen pointer there is no point in connecting peripherals to control a pointer, although in theory such Bluetooth devices can be paired with the iPad.
The "touch pad" on an iPad is basically the mouse.

Yes, you can use gmail on the iPad.
No, but you can purchase the camera connection kit for $30, which lets you use usb devices such as, keyboards, external hard drives, etc. You can use almost anything but a mouse... Hope this helps.
You can search and apply for jobs on an iPad, you can use an iPad for email for work and you can get a job writing apps for an iPad. The iPad is a tool for work, but you will still have to interact with people and use regular computers as well.

Yes. Facebook has made an application for the iPad.
Only if you want to use it on your 3G iPad.
