Welcome to the fun helmet. For accessories I would reccommend a ball starter, ball puller, patch puller worm, bore brush, bore swab, pan primer, powder flask, vent liner pick, and lots of flints.
You might want to try a cut flint( T/C, etc), or a knapped flint(Traditions , etc) to see which works better in your rifle. Depending on the twist in your rifle, you may want to try round balls, or conicals and see which shoot better. Start shooting at 60 grains and work your way up by 5 grains and see how your groupings go. Once they spread stop and back off by 5 grains seemed to work best for me. As for safety, I do not carry a flinter around with a charge in the pan. I load the pan when ready to shoot. As for powder Pyrodex works, but I have switched to 4f in the pan and 3f in the chimney. When pouring in your powder put a feather or pipe cleaner in the touch hole as to leave a path for the flame to go so it doesn't have the fuse effect. After priming the pan, tip the gun to the side as to get the powder to get away from the hole so when it lights it sends a flame right into the hole. As for cleaning, pull the barrel from the stock and place into a bucket of water with a little soap and ose the brusk up and down a few times. After that use a cleaning jag with a patch in the same way and you will get a suction effect, do this for a few strokes then pull out of water and dry off inside and out. Lubricate, store and shoot some more! I thank those who helped me with this knowledge when I started and love to pass it on. Anyways now that you got me going, I casted about 80 Lee REAL conicals for my flinter today as she eats those right up. So hope this helped a little and if you have anymore questions, post away and we'll try to help out.
