1) How can I tell what voltage it's set for?

3) This Mac has been sitting unplugged for a month; is CRT discharge necessary?

1) The voltage should be on the agency label on the back of the Mac. However if you suspect the analogue board has been replaced, THIS THREAD should help identify it.

2) Discharge is probably NOT necessary. Generally letting it sit for 24-48 hours is enough. But better safe than sorry.
