Start to study. There is a test with 260 (I think?) questions in a pool. When you take the real test you get 32 random questions out of the pool from different sections. It takes about 15 minutes to complete the test and only costs $14.00.
You can study online using the EXACT question pool you'll get questions from in a real exam session. If you pass these tests on the internet, you will pass the real test. The only difference in the real test is the order of the answers.
Here are some places to start practicing.

This place is good. However, the way this works is if you take all 100 of the practice tests, you will have sampled all the questions in the pool. This is not my favorite study website, as some questions are repeated on every test. If you get those questions right from the get go, then it's a waste of time to keep answering those questions on later test(s).

This is another practice site. You register an account and log in when you study. This site is adaptive and is suppose to give you the same questions over until you get good at them. The questions you fail will keep coming up.

This is my favorite practice site. It is like HamBoozler, as it is adaptive too. The best thing about it and is an adaptive thing that keeps throwing you questions until you score well consistantly. However this one actually gives you statistics. (Percentages of right answers for specific questions, percentage of how well done overall in tests. Etc.) I like this to keep track of how well I'm scoring on tests.
When you are ready to take your test (75% is passing in a real exam. Go test when you make 80%+) you can find a testing location here:

Punch in your ZIP and you'll find the locations with date/times. I went to the Lockheed Rec Center in Fort Worth for mine. All you do is show up with $14 and take the test, pass, wait a week for processing and before you know it the FCC has your callsign and your ready to transmit!
The test is easy. I just got my callsign last Friday. I haven't made a real contact over the air yet, I'm still trying. I've been working this whole week and nobody will answer my call at 3am on the nightshift. ;-)
I am civillian certified now
You lost me on that, what?
You can become a member of ARES or SKYWARN without being a radio operator. There is a certification you go through for disaster management and how to handle diasasters. You learn how to watch cloud patterns, and how to aid in the event of an emergency. You are not discounted from participating in these groups. They have parts of the group where people make calls to neighbors and other skywarn members to keep them up to date. Radio operation isn't the only part of operation these groups handle.
You can participate without amateur licensing.... but it sure limits your options and makes communication harder.
