Okay, JG, I'll wade in.
Thorough cleaning: take the barrel out, fill the bore with warm water, maybe a little soap (anything will do) run a patch down the bore on a correct size jag and blow the water out the flash hole. Do this several times. Then dry with patches and put whatever lube/preservative in the bore that you like. Do this before storing the gun for a while.
Less thorough, while shooting often: use alcohol/murphy's oil soap, or whatever of the dozens of prepared cleaners out there for sale. Soak a patch run it down the bore, repeat with new patch until it comes out clean. Get your breech plug scraper out and twirl it around on the plug face and then get the crud off the scraper with a patch. Then lube the bore.
spray your lock with a bit of windex, or somesuch spray cleaner until black crud quits coming off it. Or put it under the hot faucet until black crud quits coming off it. You may have to wipe with a patch with this method. Dry it and then spray on your favorite lube/preservative.
Wipe the barrel outside with any of the above. Preserve with any of the above.
This will get you started without overly complicating your life.
Soon you can graduate to mink oil, bear grease, moose milk, moose snot, or whatever you eventually prefer. What ever way you go you will be okay. Your gun is likely made from modern steel and modern wood. The only way you can hurt it is to not clean it for a year or two at a time. I know guys who let there dirty guns set around for months without cleaning. I don't recomend this at all, okay? But don't worry about the process. Enjoy shooting and cleaning and learning about both.
Everyone here has an opinion about the optimum way of doing things. Examine their ideas and choose what appeals to you. Clean and lube at least moderately and you will pass your gun along to your children and grandchildren.
But mostly enjoy.
God bless.
