Ion-dipole interactions are the strongest intermolecular force and therefore stronger than hydrogen bonding and therefore ion-dipole interactions have a higher boiling point.
I think the hierarchy is ionic>ionic-dipole>hydrogen>dipole-dipole>london forces (in terms of strength of interaction). Higher the strength, higher the temperature it needs to break the bond so higher melting point.
Ionic bonds will always create the highest boiling points, hydrogen bonds are just exceptionally strong dipole-dipole interactions. Follow the general rule ionic>hydrogen bonding>dipole dipole>London dispersion
Yes, I think that you can usually assume this. Hydrogen bonds only occur with Nitrogen, Oxygen, and Fluorine since these are the most electronegative atoms, so they can result in relatively strong dipoles.
