I agree, make it run and go drive it. Focus on your driving skills first, trust me it's the best thing anyone can do, especially when you're less experienced.Wow. That is awesome.
I would seek out the race/other history of the car...methinks that car has had quite some time on the track judging by the stickers.
If you find old photos and documentation of the car you should keep it as-raced!
There are probably few remaining Alfetta cars like yours which haven't been seriously updated/modified to continue racing, or rusted/wrecked to pieces. Keep the patina! Enjoy it.
