Answer 1

As #Jarmod correctly pointed out,
In your first template, export the s3 bucket name using { "Ref" : ",S3Bucket" }
In your second template, you don't have to create the bucket again.you can use the exported value from the first template if you want to refer the bucket name from resources. But i don't see any of the resources in the second template refer the S3 bucket name.
