You can use sstable2json and json2sstable cassandra tools

Check out Datastax documentation on the same and this too

Usage: sstable2json [-f outfile]  [-k key [-k key [...]]]
Usage: json2sstable -K keyspace -c column_family  

You can always execute cassandra-cli commands in file

cassandra-cli -h HOST -p PORT -f fileName

You can load all your create statements in to a file and execute this command

To get cli scripts to create keyspaces and column families use following command in cassandra-cli interface

show schema

But incase you wanna create a cluster of two nodes. You don't need to do all the above. Just starting the other node with different token range and same cluster name would do. Cassandra internally will manage to stream the data and schema informations
