There are lots of different ways people clean & lube their autos.
You're on a good start. Field strip and clean the barrel with a good solvent. Hoppe's is good, however I've started using RIG #44 and find I like it better. Use solvent on a patch to clean the breechface, feed ramp and down the magazine well. (Note: Foam swabs are good here too and better than cotton since they leave no fibers behind). I also clean the barrel bushing (if equipped), the frame's dust cover below the recoil spring and wipe down or soak the spring itself.
For lubrication I use Tetra grease on the rails (inside/outside) so there's a fine film. Also apply some to the bottom rear of the slide where it contacts and cocks the hammer. A film of oil around the inside of the bushing and a drop on the link pin (1911's). Don't forget to lightly oil the locking lugs and their slide recesses. Add a drop of oil or two along external extractors to ensure they can still pivot easily.
My main rule: If I see wear spots they get some kind of lubrication.
Depending on how much you shoot, about every 1500-2000 rounds, either remove the firing pin & spring to clean the FP channel or hose it down with a good degreaser to remove crud. Lubricate with about 2 drops of oil fore & aft and work the pin back and forth (excess can be removed with compressed air). On 1911's this is a good time to remove, inspect and oil the extractor.
Don't neglect cleaning and lubricating your magazines either!
That's all I can think of for routine maintenance at the moment.
