There's a complete run-down of resto glyphs in the sticky. A couple of solid choices for pre-80 might be:
Regrowth: 20% stronger heals, good stuff.
Swiftmend: Not consuming the HoT is nice, especially when tank healing.
Rebirth: 'Cause you are going to lose people while everyone is still learning the ropes.
Healing Touch: Put 5 talent points in Naturalist, and this is a nice quick heal pre-80.
