Well, with +healing giving bonuses to +damage now, it is easier for a holy paladin to farm. I no longer have much trouble quickly taking down mobs while I'm holy (but then again I'm am geared very well, so I have a good amount of damage from my healing).
Holy is definitely the safe spec for a paladin to go into. You'll more than likely find more groups as such. Ret paladins can do decent damage, and we were buffed with the last patch, but you finding a group solely depends on how people perceive them on your server and how well you deal out the damage. Since you are not in a guild, and have mostly healing greens, it would be hard to just stick on healing gear while still ret spec for some instances (given the fact that you'd probably be in a group with gear similar to your own).
As for a holy damage build, there aren't too many talents for that in the holy tree; holy shock being the best. You can put the rest into ret. Here is an example spec
that might be useful. Some people would put it in Purifying Power, but I rarely farm undead/demons so that wasn't really useful to me. As well, if you have a lot of intellect, switch out Imp Sanc Aura for more points into Holy Guidance. From this spec, I'd judge Crusader then spam SoC while also spamming Concentration and Holy Shock.
