Ret pallys gain a little range with Repentance, cheap instant cast 20 yard incapacitate. Only works on humanoids, but it's fantastic for pvp. As a BE, the number of interrupts i have against casters is incredible.
Talking about pvp, before you get those ranged abilities, you are quite vulnerable to being kited by a player good at it, hunter or mage or similar. Breaking line of sight is quite important, as is creatve use of divine shield and being lightning fast with your Blessing of freedom/cleanse.
