Use 'iwconfig' to list devices. If you use ifconfig wlan0 down, then use ifconfig wlan0 up after the macchanger.

airmon-ng start wlan0 tells you 'mon0' is the monitor mode device so use that.

ie:
airodump-ng mon0

Most tutorials on wep / wpa cracking instruct you to spoof your MAC address but its not required.

It's a total waste of time, fingers and keyboard, in my opinion.

Stop using macchanger and prove that you can do the basic steps first. I have the strangest feeling you're not going to be able to, but I can't confirm and all that (it being that holiday today that falls on the day of the ol' time worship of the sungods).
