ok, specialty grains with extract is what I do. you basically get them in a muslin bag (usually cause I order them from like NB, Austin or Midwest).
And hopefully a muslen bag for the hops. Ok, so you heat some water put the bag of grains in steeping it (like tea) for about 1/2 hour, then boil and put in the malt extract. After that you put in the hops. and boil (hopefuly you can do your hops like tea also). Simple.
As for LME and DME, they come in light, amber, golden and dark. In theory, you could make brews with them and hops, but usually it is grains with Malt extract
