Still-a-noob cleric gear questions

[eddyystop]

I'm a new player who got a goodie cleric to 55 going CB -> MM -> CoM. That route provides nothing in the way of gear. The best items I have are a Springwood Club and Charred Guardian Shield. I have about 2k plat. Yes, sad.

1. What's the best wis/resist gear my cleric can reasonably solo/quest during non-evening EST hours?
2. Where's the best place to group for cleric wis/resist gear? I understand these are likely preplanned groups.
3. Where's the best place for a cleric to solo farm plat or vendor items?
4. What items should I try to buy?

Sorry for such basic questions.
