I would not worry too much about tarnish on the wire. It might be a good idea to clean off just the contact area on the ends before terminating them. I don't think it will make much of a sonic difference for the rest of the wire unless it is terribly pitted or corroded. Happich Simichrome is my favorite metal polish if you want to get through the corrosion and put a beautiful shine on the ends.
Except that tarnish is not silver oxide but silver sulfide, which is not conductive. It is a good idea to remove it, and many new polishes are non-abrasive with protective conditioners left behind to prevent tarnishing. Getting a product as above mentioned, or even something simply from Ace Hardware can prove to be positive. I am not familiar with the pros and cons of cigarette ash...
