Yes, you may need to download a driver for it. I would do a Google search for the type of interface and its compatability with garageband. From there you should be able to find out what if anything you will need to do.
Garageband works fine with midi equipment connected through a USB cable.
You can use the midi output from the EZ 200 to control Garageband. You will need an adapter to connect the midi lead to the Mac's USB socket. (See links below)
Midi to USB cables run from some sort of musical device (electronic keyboard, electric guitar, etc) to a USB port on your computer. You can use it to transfer midi files (music files) into your computer.
One can buy a MIDI to USB interface cable from Amazon for $4.09. One can also purchase this type of cable from ebay, Cable Depot, Maplin, Roland and Staples.
If the MIDI keyboard is not class compliant as a USB device (ie. needs a driver installed for a Mac), it will not work with an iPad. In addition, if the iPad shows an error about the USB power when the keyboard is plugged in, then it is drawing too much power from the iPad USB port and will not work. The only way to get an over-current keyboard (and many require more power than the iPad can provide) is to use an AC adapter on the keyboard if it can use one, or use a powered USB hub that is compatible with the iPad. The Belkin ones seem to work fine, but some others do not.
Most modern MIDI devices come with a USB link that passes the MIDI signal to the USB socket of the computer. If a USB connection is not available then a MIDI to USB adapter (See links below) can be added to connect the standard MIDI sockets to the USB socket. These are widely available from various manufacturers at varying prices. The Mac usually recognises when a MIDI device is connected but they can be configured with the Audio & MIDI setup utility found in the Utilities folder within the Applications folder.
No. Akai MPD are USB MIDI controllers and work with programs with MIDI capabilities. Audacity doesn't do MIDI.
The usb cable extension is made by another usb cable. The cable is made with one usb connecter and 1 usb connecter. You can simple attach the extender cable to your usb.
To transfer the MIDI data a MIDI to USB adapter will be required (See links below). This will probably be recognised by the Mac (using Garageband etc.) once connected or can be configured with the Audio MIDI Setup utility in the Utilities folder within the Applications folder.

A MIDI controller sends MIDI note messages to another device by MIDI cables or USB to a computer. If it is strictly a MIDI controller with no onboard sounds, it will have to connect to another MIDI device or computer to make sounds.
It will not work with your camera. You need the Fuji multi USB cable
