Getting started with Selenium RC/Eclipse (Java)

Hello, colleagues!

Please help me to get started. It is very confusing because there are
newer version of Selenium RC, but all tutorials are for old ones.

I have set up Eclipse as http://img21.imageshack.us/f/eclips.png/

1) Can you please tell me whether the set up is correct? Which libraries I don't need? I will be doing very simple test cases (open/verify/close).

2) I have the following code from IDE which I would like to import to Eclipse:

Code:

package com.example.tests;

import com.thoughtworks.selenium.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import java.util.regex.Pattern;

public class Untitled extends SeleneseTestCase {
    @Before
    public void setUp() throws Exception {
        selenium = new DefaultSelenium("localhost", 4444, "*chrome", "http://en.wikipedia.org/");
        selenium.start();
    }

    @Test
    public void testUntitled() throws Exception {
        selenium.open("/wiki/Boeing_XP-15");
        verifyTrue(selenium.isTextPresent("aircraft"));
    }

    @After
    public void tearDown() throws Exception {
        selenium.stop();
    }
}

Can you please tell me the step by step instructions of how to create a class (test case) with this code in the Eclipse and run this simple test case?

Thanks in advance.
