Ok, I'll remind you later when the time comes. You know, it probably isn't much of a job to throw in the Hero's sound effects. After all, NPC's don't need Sound Sets; only User Controllables do.
That limits your work to the... 13 Heros of LoA, plus only a few Quest units.
How about this:
Dwarven Rogue - "Rifleman"
Dwarven Warrior - "Bronzebeard"
Hell yeah, PWN!
Elven Druid - "Druid of the Talon" (although I personally like "Druid of the Claw, the model seems more like the DotT."
Elven Archer - "Archer". The "Shandris" Sound Set, if there is one, may be better though.
Goblin Engineer - "Goblin Tinkerer" (You mispelt Engineer in your FanSite Kit. Please make sure it is correct in the map!
)
Goblin Thief - Gawd... no idea. What does the WC3 Goblin Alchemist sound like? (Would it fit here?)
Human Mage - Does Medvih have his own WC3 Sound Set? If not, "Priest". The fact that priests say things about Light Magic shouldn't really matter. The fact is you need a sound set, and your Medvih model seems to fit the "Priest" Sound Set Decently.
Human Paladin - "Uther Lightbringer"
Hell yeah, PWN again!
Orc Alchemist - I think one of those strange Orc Warlock Campaign units has a good Sound Set for this guy.
Orc Berserker - "Grunt" is always nice, but if you find something better, tell me!
Orc Hunter - "Headhunter" or "Batrider"... I know batriders have strange soundsets, but it's much more creative than the regular old "Headhunter" Sound Set.
Undead Stalker - "Sylvanas"s' Sound Set isn't bad, but I have a feeling you'll just go with the "Dark Ranger"
Undead Warlock - "Lich"
