1. No difference, although I'd prefer clay because, as long as a correct watering and feeding regime is in place, clay breathes, allowing a bit of excess moisture to escape.

3. Yes, if the plant is not fed the correct amount of food and water, but many plants will stand being crammed for years in a pot if they're getting everything they need.
