Starting with Roborumble Questions

Seeing as I was going to try this on a RP2 soon, I was going to get it working on my laptop first. But I had a couple of questions for those in the know that don't seem to be answered on the page or the discussion:

1) Should we always run the latest version of Robocode available for the rumble? (Starting with Rumble page mentions several versions of Robocode, none of which are the latest) 2) Does it matter any more what version of Java we use to run the Rumble with? 3) Does it matter if I interrupt the rumble process at any time? Will this corrupt the results? Or can I run a few battles, quit, start again etc etc.

Thanks! (I might turn the answers into an FAQ on the rumble page)
