Recently, I briefly worked with someone who was born in Czechoslovakia and moved to Canada as a child. Of course, I couldn't waste the opportunity to pick up a few Czech words and get an idea of what this language is like from a native bilingual Czech/English speaker.
For a native speaker of English, Czech is relatively complex and irregular. There are also a few sounds difficult to produce, including one particular sound (sort of a cross between a trilled r and a zh, if you can imagine that!) which can be very tricky.
A few facts about the Czech language :
Czech is the official language of the Czech Republic (of course) and is spoken by Czechs living around the world. It is also one of the official languages of the European Union.
As a West Slavic language, it is closely related to Polish and Sorbian, as well as being mutually intelligible with Slovak. Like Barry Farber says, you'll get a discount if you also learn one of these other related languages, but also to a lesser degree Russian and other Slavic languages.
There are very few published courses and resources to learn Czech, so our choices are limited.

Teach Yourself Czech
The longstanding Teach Yourself series has always had a wide variety of languages, and fortunately they have a course to learn Czech. The coursebook comes with two audio cd's and is available in most bookstores or online. Be forewarned, however, that this course is not for the traveler or casual learner. Czech grammar can be complex and difficult and this course doesn't attempt to whitewash or avoid that. This is more than just a phrasebook.
