To question 1, of course -) It's the encyclopedia that anyone can edit, after all. Probably won't even have to ask.
To question 2... to do that, you have to move the page; there's a tab for that. If you've been here for more than 4 days under this account, you should be able to move a page. To be honest, I've been here a while and have never moved a page, so I don't know the exact mechanics, but I'm pretty sure what you'll want to do is move your userpage to WebTrain or something similar. This will copy the content from your userpage to a newly created page, and your userpage will become a redirect, i.e., ""#REDIRECT WebTrain"" will be the only text on your userpage... you will need to remove this to prevent your userpage from redirecting to an article (not good). There's also the option to move the talk page with it, but I don't think that that's a good idea... probably better just to copy/paste everything in that instance. But don't worry about q2 until you're done editing.
I'll ask around about page moves... These type of things tend to have a GFDL stipulation somewhere somehow, but I may be wrong.   "
