I'm not a mod, so I can't answer these all, but-
1. Yep! Several people have done this. Just make sure you finish it at some point.
2. Yes! There's a reference stickied in the Guides category.
3. Hitting the filter is okay but don't try to evade it. Swearing at other users isn't allowed.
4. I don't see why not, but I'd wait for a mod's response.
5. Not a mod and can't answer this. I can say that the reason cross-site trading isn't allowed is because some sites have such an integrated impact on pet site economy and its easier to keep everything to the site itself, if that makes sense.
6. Should be fine as long as you aren't making a majority of your posts solely keysmashes.
