Consider the usual factors. AAoA would change based on backdating. Utilization should improve with more available credit. You'll incur a hard pull. We can't tell you that you'll get or lose X points. Seems like it should be generally positive for you.

Your call to make. You haven't given us enough info to attempt to make a recommendation. Do you no longer have any need for it? How concerned are you about fraud? Are you able to monitor it even if you don't use it? With the way closed accounts continue to report and with AmEx backdating you won't really see an impact on AAoA from closing. You will, however, immediately impact utilization by closing it unless you can transfer the available credit. Again, consider the usual factors that play into credit scoring.

Impossible to say. Having X limit with a creditor doesn't mean that your next card with the same creditor will necessarily have the same or similar limit. My first recent AmEx had a $12.5K starting limit and went to $25K. The next one only start with $6.9K and just recently went to $20K.
At the time I got the $12.5K AmEx Chase gave me two $25K cards so it depends on the creditor and their critieria as well.

Good is highly subjective regardless of topic. You need to tell us what you're looking for if you want that question answered. It is of no perceivable benefit to me but YMMV. Why are you considering it?
