Class selection advice, please (for the indecisive min-maxer)

Pulling and tanking?

That's monk.

Healing? Cleric or shaman are more powerful in some circumstances, but a Druid can heal and fund your monk by whoring out its ports.

Monks are just broken in Velious; their constraints in unexpanded was weak itemisation, a deliberate design decision.

By the end of velious they can cap their worn AC (which coupled with their defence skills lets them avoid and mitigate hits better than a warrior), they have excellent ratio weapons, which capitalises on their improved damage tables (in unexpanded they were intended to use their fists or crappy ratio blunt weapons). They have incredible white damage aggro, but can also drop aggro at a whim. They can also self heal without mana which works around the thing that tends to make soloing difficult. Oh and they can self haste effectively, letting them operate at close to max dps unsupported.

Absolutely a min maxers class.
