Need Help with a few things

[Homura]

Ok, first off, I was looking for a working action replay for the gamecube from America where you can edit in or add codes yourself for the Pokemon Colosseum and XD Gale of Darkness game, but I had no luck in finding one

Action replays aren't sold in stores anymore, since it's a discontinued item for at least half a decade, if not more. Your best chances are online stores or online auction sites such as ebay. If you have no access, tough luck and just play the game like it's meant to be played.

help on how to turn on the mastercode on the XPloder Cheat System device for Pokemon Emerald and figuring out which code it was from that site.

I guess if you need to figure out which is which, you can turn everything on, see what cheats you have on, then systematically turn off lines one/two at a time and see when all of your codes stop functioning. Or just wipe everything and start over with the codes you found on your site. In general, asking for help about a particular cheating device on a site that isn't dedicated to said cheating device will give you no help. You're honestly better off looking for a forum that is dedicated to your cheating device.

And second, how exactly do you report abuse to your ISP? They need all pertinent details or they won't take action and I was reporting myself. You have to report it within a few days time or else they won't take action either. I've learned this the hard way when I didn't report someone immediately or save all the chat logs. What can I do about that?

You provide absolutely no detail. However, it's very rare for an ISP (i.e. internet service provider) to do anything about any particular user on the internet, considering that they may not even be using the same ISP in the first place. You mentioned chat logs, so I'm guessing something happened on AIM? If so, just block the user and go on living your life as normal. There's really no need to contact any company that'll just ignore you for the most part.
