Here are a few suggestions.
Balls, my Hawken performs best with a plain-patched round ball, be sure to grease the patch to make it easier to load. And lead balls were used to kill deer long before conical bullets showed up.
Short Starter, a short ramrod used to start the ball into the bore, then use the ramrod to seat the ball.
Capper, holds a supply of percussion caps and has small fingers to hold and seat cap, great when wearing gloves or just cold stiff fingers.
Powder flask and measure, used to store and dispense loose powder.
Powder, have not tried the pellets yet but mainly use Pyrodex, measures like black powder and has the same smoke and flash but cleaner burning and easier to clean up.
When you find a load your rifle likes place a small mark on the ramrod to insure the ball is seated to the proper depth.
Good luck on your new smoke pole it will provide many hours of enjoyment.
