I can't answer about whether the manual contains all of the information that you'll need...but I bet that it does.
All guns require the exact same cleaning and maintenance supplies. Brand-name is not important, as long as the stuff has a good reputation. I have always had good service from KG-brand chemicals, Hoppe's #9, Birchwood-Casey, and, currently, Ballistol. Others are just as good. This is not something to obsess over.
You will need either a really good cleaning rod, or a BoreSnake, or both. (I use both.) Maybe a rod will come with your gun. I suggest that a steel cleaning rod is better than an aluminum one.
You will need some sort of patch-holding tip for your cleaning rod, and at least one bronze-bristle bore brush.
You will need an old toothbrush. Also, a brass-bristled, toothbrush-looking brush is another good thing to have.
You will need hundreds—nay, thousands—of cotton patches of the correct size.
You will need a spray-can of "gun scrubber," a small tube of high-quality gun-lubricating (not preserving) grease, and a lot of high-quality gun oil.
The very first thing you must do to a brand-new gun is to remove all traces of the sticky preservative grease with which it was coated at the factory.
This is a very useful job in more ways than you think: You will learn to detail-strip your gun, while you're cleaning the grease off of it. Then you will learn how to put it back together again. Follow the manual's instructions to the letter. If something goes wrong, read the manual again, this time more carefully.
Places where there are sliding or rotating metal-to-metal contacts get at least a little oil. Many people prefer lubricating grease here. I go either way, depending upon my mood that day.
Everything else that's metal gets a light coating of oil, which is almost immediately wiped off. Your gun should not feel oily, nor should any part drip oil. (Your kit should now include a soft cotton cloth that feels a little oily. Use this cloth to wipe the gun down, after every time you've handled it.)
Get those snap caps. Use them for dry-fire practice. Daily. (Ten minutes a day is enough.)
When you dry-fire practice, take every bit of ammunition out of the gun. Check the chamber and the magazine well. Check the chamber again. Now take all of the ammunition out of the room in which you'll be practicing.
Come back and check the gun's chamber once again.
Now you can load-up with snap caps for practice.
Dry-fire practice is supposed to help you learn how to press (not squeeze) the trigger, while maintaining a proper sight picture and complete concentration.
Use a blank portion of interior wall to do this. Do not use a photo of your mother-in-law, or the TV.
Even aiming at a blank wall, you will see whether or not your sights waver excessively, as you press the trigger. Work toward eliminating most of the waver. (You can't get rid of all of it, so don't try.)
Now you are well on your way toward mastery of the pistol.
Let us know how you're doing.
