Extreme,
Since you have been flying helis, I assume you can figure out the radio stuff. you need to fix any broken balsa with glue and covering. Be careful to make it as strong as the original without adding too much weight. Almost anything can be fixed.

If the engine was running good, the discoloration might not be a problem. Since it ran 4 months ago, I would first try to fire it up!

Get some help to fly it. It is different than the Heli.!
