First time cleaning a luger

[azgunnut]

I bought a shooter luger recently and had Hugh add a new barrel to it. I took it out to shoot today and it worked great. On the way home I realized I know how to take the gun apart and clean it, but I don't know how or with what to lubricate. I searched lubrication, lubricate and lubrication points, but did not find a good answer. What parts do I lubricate and what should I use as a lubricant?

Any info would be great. I realize you older forum guys have probably heard this question a million times, but I'm kind of new hear and would like to find out the right thing to do.
