Also, is asking someone to show you tips in openings in a general sense, such as for Queen's Gambit Declined, as opposed to specific game moves that we are currently playing?
I would say yes, that is allowed. At some point you pick up certain pieces of knowledge about openings through books, internet, experience, coach, etc. You are certainly allowed to apply that knowledge to your games. Otherwise, while you had games going, you could not try to improve by hiring a coach and working on your game in total without regard to the specific day-to-day changes of your gip's. A coach, without knowledge of your games, would be teaching you Chess and not game xxxxx, move 16 at RHP.
A strong word of caution: You can probably see how thin the line might be if >you< are asking the questions. Don't ask about the specifics of any game in progress and you should be fine.
