Prot/Holy Hybird for Low-Level PVE

Trying to get my friends into WoW, and wanted to get them onto this server to level together for fun. They'll probably all be playing DPS though, so I was wondering if any of you had good guides for a Prot/Holy hybrid I could play for 5-mans with them? Obviously I'm not an ***** and know this is a rubbish idea for playing properly, but just for playing casually (and probably not even getting to a high level at all) is there a way I can optimise talents and stuff to be able to tank AND heal in 5 mans and when levelling together? Thanks.

A little late but i hope this will help you.

You can tank, heal and dps dungeons as ret till outlands.

When i level a paladin i end up doing all 3 at the same time once i hit level 50ish.

Tanking might be a bit hard if you're new to it.
But it gets better the higher level you become.
Make sure to LoS pull the mobs.

Get "Judgement of the Wise" talents asap since this will help you sustain a healthy mana pool ALOT.

After this take "Art of War" for instant flashes of light.

Skip the 2h speciacialization.

Try to avoid using holy light since the drains your mana pretty fast.

Get the following glyphs.

Major:
Flash of light.
Holy Light.
Righteous Defense.

Minor:
Lay on hands.
Blessing of kings.
