Best way to terminate speaker cables ?

I am buying some used DH lab Q-10 biwire cables from a fellow Audiogoner that have no connectors on the speaker end and am looking for suggestions for how to "terminate" them. My speakers(Shearwater Hot Rods) have binding posts that accept bananas or spades. Should I stay with bare wire or get some spades or bananas ? Where can I get some spades or banana connectors that are reasonably priced and is there any technique for attaching the spades/bananas ? How should I clean the bare wire ends once I receive them ? Thanks
