You can lose the filters - almost everyone does. Yes to fluffy-type pipecleaners and yes to a cheap multi-tool scraper/tamper or, as many prefer, a big-ass nail with the point ground off or a golf tee. They have golf tees in Texas, do they not?
The cob that's best is made by Missouri Meerschaum; China and Korean imports kinda suck. No need for extra stems if you don't sit on the pipe or starting chewing on it real munchy-like.
Carter Hall, Prince Albert or Half&Half are good starters. If you can't find any at a grocery or drugstore check out jrcigar.com pipe section. Lots of online options.
