01kipper: I just discovered I have a few unredeemed Steam keys on Groupees. Is it OK to give those away on Steamgifts for this group? (I don't want to break any Steamgifts rules).
Yes, it's okay, because those keys are still good to use if they never were used before, and bundle games are also okay to gift ;)

You can't for now. In the first page is all the information you need:
