Yes to all of the above.....and it seems that chain lube is a matter of personal preference. If you think about it, a chain is a series of small parts connected by little pins so all the parts can pivot about the one next to it. Why would you not want to keep those parts clean and well lubed?
A clean and well lubed chain is quiet, makes shifting easier, and prevents costly repairs. I clean the bike chain by wiping if off and by using a chain cleaner with degreaser....with regularity. The Katy can be dusty so the chains are cleaned after each ride on it or similar trails. On long rides I clean the chain and relube along the way.
There have been lengthy discussions here on what is the best lube to use. I use Ice Wax but there are many kinds on the market. Google "Sheldon Brown chail lube" for a good article on the subject.
