Some questions about the Paladin journey to 60

Hello everyone!
I played WoW during TBC, Wrath and gave up before the 2nd major patch in Cata.
Now I have returned to Vanilla and I decided to be a Paladin. So I am Alliance (almost always been horde).
I've read almost every thread about the paladins here and I still want some help with the class considering the leveling aspect.
Right now I am lvl 20 specced in consecration. Should I try to AoE farm? Should I use 2h or 1h+shield. Should I go for the protection tree or should I put points in retribution to get Seal of Command?
Also I would like to ask the people who already have high level paladins how was their leveling experience? How did you guys do it? Tanking dungeons or healing? Just questing?
Any help is appreciated.
