If you have 2pc T5, there's a very effective, low threat method to DPSing using Arcane and frostbolts. The idea(as I remember reading it) is that you need enough mana regen with Mage Armor and Arcane Meditation that spamming frostbolts costs less mana than you are regaining per cast(you will almost definitely need a shadow priest for this). From there, you spam Arcane Blast until you're low on mana(using a gem and a pot early), then pop Evoc and do it again. Then, when low, you cast frostbolts until you have enough mana for another decent sustained spam, or a potion/gem timer comes up.
For that to work, you spec a fairly standard 40/0/21. It has the theoretical potential to do as much DPS as 2/48/11. I've seen it work. The guy in my guild running it routinely does almost as much damage as me on bosses(occasionally more) and utterly destroys me on trash mobs(no imp scorch up for long periods means I do a lot less damage).
The kicker here is that now you actually need to stack a fair bit of spirit. Which isn't too hard if you focus on getting your tier gear, which is loaded with the stuff.
Now, on to your other question about how hard your frostbolts need to be hitting...well, I really can't tell you. A lot of factors will come into play here, and you may acheive the same overall DPS at a lower damage per frostbolt than someone else does because you have more crit or haste than they do. Just follow what CalenciaBlue suggested as far as spell damage/DPS and you'll be fine.
