I play a Thief and have decided to throw some Destruction in, so my Destruction is low, so I'm struggling. What enemies have what magic resistances? For example, what's resistant/vulnerable to Frost magic and so on?

Well Trolls and vamps have low fire resistance.
When you use a Destruction spell on a valid target, you get XP equal to the base mana cost of the spell used. The more mana the spell costs, the faster the skill levels. For general use, you'll want to use Shock element spells, as they tend to have higher Mana cost than the other element. This actually works out, because there's only one creature in the game that has an innate resistance to Shock Damage (the Shock Atronach), and you hardly ever see it. Be warned, though, that I have had enemies resist shock randomly; I'm assuming that they had a Potion of Resist Shock in their inventory that they used when they saw me using Shock spells.
Anyway, since you're a thief, Runes are going to be a good way to level, at least in the early Destruction levels. Just sneak in and throw it in an enemy's path. Just be warned that I've heard that Runes are a bit bugged when it comes to stealth: apparently, once they go off, the enemy knows exactly where you are when it goes off, even if you're hidden. Cloak spells are also nice, but while you could sneak up to an enemy and electrocute something to death, I have no idea how they will react to the damage if you're hidden. They may turn right to you, or they may go wandering off out of range of your cloak.
EDIT: Also, keep in mind that the game doesn't care how much damage you inflict; all that matters is that you use the spell and it hits a valid target. Wandering through the wilds zapping every bunny, fox, elk, moose, etc. will earn you plenty of XP. Even more so if you're using the Mage stone. Bandit camps and ruins are also nice; most enemies will be pretty weak, so you can take them out easily. Just don't kill the boss, and they'll respawn pretty quickly, allowing you to come back in 10 days and do it again.
