A thermometer, an adjustable burr grinder, and either one of: a high quality drip brewer, a hario, or a french press. I prefer the hario for ease of cleanup, personally, but some people consider non-french press brewed coffee to be heresy. I think it's cool to try to roast your own once or twice, but roasters cost a ton and cowboy coffee (roasting in an open pot over heat) produces a ton of smoke & chaff. Mostly it made me appreciate the skill involved in roasting :) The big thing is to mind the temperature of the water (and use good water), making sure you're using freshly ground whole bean coffee, the amount of grinds vs water, and the quality/freshness of the coffee beans. There's a ton of good advice online, I hope you find something that works well for you (and that my humble advice is useful)!
