Answer 1

If you have the groups defined in your cases, and you want to specify the group in your pom, then you can do the following in your pom. By default, the test phase uses surefire plugin, but you can define the following explicitly to have your groups
<plugins>
[...]
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<configuration>
<groups>functest,perftest</groups>
</configuration>
</plugin>
[...]

Answer 2

What I typically do is defining a test cases which I want to run under src/test/resources/testng folder, so let's say you will have
src/test/resources/testng/testSuite1.xml
src/test/resources/testng/testSuite2.xml
Now, you can run these suits with simple command like
mvn verify -Dtestng.suite.xml=src/test/resources/testng/testSuite1.xml
Sample TestNG file
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="seleniumTest">
<test name="All Components">
<groups>
<run>
<include name="Some group" />
</run>
</groups>
<packages>
<package name="org.package" />
<package name="org.package2" />
</packages>
</test>
