An occasional info-dump is okay, as long as they don't go on for pages and pages. But the best way to convey information to the reader is the way the masters do it: Teach the reader by teaching a character. Have a character learn the information so that you as the storyteller can reveal it to the reader. The critical thing here is that the character learning it absolutely cannot know the info already. Nothing makes me roll my eyes faster in a story than when one character tells another, "As you know..."
By the way, the best "how to" guide for writing I have ever found is A.B. Guthrie's Handbook: A Field Guide to Writing Fiction. There are lots of great books out there on things like plotting, characterization, dialogue, theme, setting etc. But when you get to the point where you're asking yourself, "Okay, how do I get the words on the page?" You won't find a better book that Guthrie's.
I think it is out of print, but if you can find a copy, don't pass it up.
