Buy clothes but don't go overboard. The beauty of being a first time parent is picking out those little outfits, blankets, bedding and the pram yourself. Most of the stuff you receive hardly gets used if at all although it is nice to receive some little outfits, not everything you pick might be to her taste and she'll want to get most things herself.
If she asks for advice give it, if not then bite your tongue.
Don't call her baby your baby.
Don't ask about overnights.
Don't pick baby up without asking.
Don't be offended if they don't want you in the delivery room/visitors for a few days or whatever. Its their time with their baby. Enjoy!
