The ensemble of parts is good, first generation "ergo" brake/shift levers, Record crank. If you like the brakes, you are good to go.
I would consider having the bottom bracket and head set repacked and drivetrain cleaned. Much cheaper than looking for undamaged replacement parts, select a shop that knows about vintage stuff.
Its an American built 3V, good bike. I like the Scott drop in bars, others and the UCI do not.
As you get more comfortable get some shoes and pedals to keep your feet in place while riding, much safer and modern "clipless" pedals are easy to disengage.
