To answer your questions:

1. No, you should never run JMeter on the same machine as the server you are testing.  
When I say JMeter server, I mean an instance of JMeter running in "server mode".  In 
version 1.7.1, JMeter is run in server mode with "jmeter -s".  In 1.7, you use the jmeter-server

script file.

2.  You can run JMeter servers on as many machines as you have/like.  One machine, 
running in normal GUI mode can control all of them.

3. You don't need to do any special to combine the results files.  Any listeners in your tests

will receive the results from all the remote JMeter servers you run.
