Well... I haven't looked up the Bianchi line from that time frame, but I would say that it was lower level, or entry level offering.....quality restoration of any bicycle is either time consuming or costly OR BOTH if you don't have the tools/skills...... I would just focus on maintenance items, cleaning and possibly a few cosmetic touch ups, then ride it. It is not a Bianchi offering worth spending any major bucks on IMHO.
If you like it and it fits and you're happy with it....just enjoy it. As you progress (digress?) into the C&V world, you may find yourself wanting something nicer....that's when you sell it to help pay for the next one ! Most of the folks here wind up with several or more bikes, suiting various purposes.....not to say that you cant find a decent all-a-rounder..... a racing bike does not usually make for a good commuter.
Spend time reading the forum here and pay attention to what the experienced and knowledgable folks here have to say about various bikes, tubesets,builders, components, etc....and you will soon begin to have a better idea what you might want ....size/fit being the most important...but then things like ride characteristics, weight and purpose begin to come into focus as well.
Either way, you now have a Bianchi....which is still a cool Italian bicycle !
