1. Yes. However, if you read the find familiar spell you can dismiss and resummon your familiar into a demi-plane as an action. You only need to recast the spell if it dies or you want a different one.
2. Correct. So to cast find familiar as a ritual is 70 minutes.
3. Correct. The warlock gains the find familiar spell, with a couple of bonus choices.
4. No. Use the imp stats from the player's handbook.
5. Sure? There's no question.
6. Regular familiars can carry items if it is logically possible. IE a raven could pickup a small pouch. Imps advantage over a regular familiar is its better attack, magical properties, and increased durability (most regular familiars have 1 hp)
7. That tag is not the imp from PHB. Also the Mephit has a similar skillset to imps and is available as a familiar to warlocks.
8. Again, the warlocks imp is a spirit taking the form of an imp, under the warlocks control.
9. The MM is designed for DMs. Not players. If the DM wants to include an imp they can bond with literally any player, caster or not.
Basically I think you would have saved yourself a lot of trouble if you just read imp from the back of the PHB rather than the MM.
