Since I'm in agreement with my buds here, I'll go ahead and throw in my 2 cents! =D But with how wordy I tend to be it may be more like a nickle.
As is implied above, unless you're really in love with this bike, it has strong sentimental value, and/or you want to keep it forever and ever Amen, restoration is not an option. A great debate in auto restorations is how much can you replace before it's no longer the same car. I think by the time you were done with this one it would no longer be the same bike.
I see bikes like this as great learning tools. It's rough enough that you really can't make it worse. Only two painted parts: frame & fork. Get some aircraft stripper and go to bare metal. Try your hand at repainting it. You can't lose. The money and effort go towards your education.
After that, tackle the moving parts and make it rideable. Don't sweat the chrome (or lack thereof), just see if you can get it going. Then if you decide to keep it you can be patient and grab up some of the plated parts here and there when you find a deal. Or not! Just ride it as is.
As long as you keep in mind you're doing it to learn and not to make it worth more than it is now it will be worth the effort.
