Use the GOEX FFg in the pan. It will work fine, and better than Pyrodex P. The paint brush and paper clip will do the job. A one-inch or three-quarter inch brush is about right. Cut the bristles short to stiften them up a little. I don't use a brush myself, but wipe the pan and frizzen with a cotton wash cloth or a patch. I do recommend you get a pan charger though. Most anything will do for knapping the flint - the back of a heavy knife blade, a six inch section of 1/4" brass or copper rod, etc.
