I'd probably go with a paladin healer as well, if it wasn't for the fact that I''ll be horde :-)
Regarding frost vs fire, I believe both will work just fine. From what I've been able to read on various forums, fire will be a bit better dps, but with more drinking for mana between fights. I prefer frost, mainly because from what I understand, the DPS difference isn't much, but it's a 1-button setup, which greatly reduces complexity when boxing. From what I understand you need to weave in scorches in the fire spec, but again, I'm very far from an expert on the topic, so take it with a grain of salt :-)
I don't know enough about frost vs fire in vanilla to say much about threat, though I would guess that frost is less threat / dmg due to talents (https://classicdb.ch/?talent#of0E0ofquZVA0c0s).
Either way, you should be fine with both specs - vanilla dungeon mechanics aren't that complicated and you'll likely be limited by your ability to CC and maintain threat on your tank way before DPS becomes a limiting factor :-)
