I don't think you'll need the tubes and and chain lube. Well, the tube may not be a bad idea depending on how often you might get a flat. The lube I keep in my car and at the house. I usually only wipe the chain down at those two places and add lube (if needed). Consider getting a rear light with a USB charger. I have a Cygolite Hotshot Pro 80.
Chain lube is probably over-preparing. I am looking at a new rear blinkie as mine is getting corroded internally. I have the Cygolite front lights and do enjoy the usb charging aspect. Additionally I carry a small battery back with me so if I ever mess up I could hook that in for a charge. Thanks for the suggestion.
