Yeah, just ask away. If you're not sure where to ask, just ask on your user page. It also helps if you keep some sort of documentation of what you're doing, it doesn't have to be fancy, but more like a changelog - it makes it easier for us to give suggestions. I'd think that the majority of the stuff is already here on the wiki, but knowing what to call it and where it is needs a bit of experience =). Fresh blood is always appreciated! So go wild with the questions.
