If 2f is all you have, go ahead and use it, it will work fine but if you have any 3f, I'd recommend it over the 2f for your rifle. It is a bit cleaner burning and the smaller calibers have a bit of a problem with fouling.
For swabbing between shots, I like to use a 1:10 mixture of Ballistol in water. If you don't have Ballistol, just use some automobile windshield washer fluid. It does a great job and it is cheap. Run a patch with the washer fluid on it down the bore after each shot, flip it over and run it down again. Then follow with a dry patch or two to be sure you have all of the moisture out of the barrel. When you are though shooting, use the same stuff to clean your bore before going home and leave it dry before heading home.
When you get home, use warm soapy water to scrub out your bore. Rinse with warm clear water and dry with several clean patches. Spray a good bit of WD-40 down your bore to remove all traces of water and run more patches to remove the WD-40. With the WD-40 swabbed out of your bore, next, run a patch with some Barricade or other good gun oil on it and your barrel is ready for storage in your gun cabinet. Of course, the rest of the gun must be thoroughly cleaned, too before reassembling it.
Now to your loading question. First NO PLASTIC!!! Use around 35 or 40 grains of powder to start with and adjust from there to get your best group. Prior to loading, place a cap on the nipple and point the muzzle downrange at the ground close to a leaf or blade of grass. Pop the cap and watch the leaf or blade of grass to see if it moves. If it does, your flash channel is open and you are ready to load. If it doesn't move, you need to find out what is blocking the flash channel. Measure your powder and pour into the bore. gently tap the side of your rifle to settle the powder in the powder chamber. Then place a lubed patch carefully centered on the muzzle. Next set your ball on the patch and start it down the bore with your short starter. Seat the ball onto the powder with your ramrod. Make sure it is seated all the way. Do not leave any space between the ball and the powder. Now, walk to the line, cap your rifle and shoot your target, Never cap or prime before reaching the line and pointing your rifle downrange.
