You have several things here. First, changing the number of replicas is easy, just create another node and associate it with a shard of an existing collection. See the shard= param on the solrcloud page when creating nodes. If you don't specify a shard, it'll just be assigned to one of the existing shards on a round-robin basis.
Changing the number of shards can be accomplished by the splitshard command. I confess I don't quite know about the number of shards per node bit... As far as separate collections, note on the bootstrap command you have the collection.configname paramater that creates a named configuration set. Then when creating a collection, you'll see the collection.configname parameter again that can refer to the one you uploaded with the second bootstrap command. You can also push your configurations directly up to ZK with the ZK command-line tool and refer to them with collection.configname when creating collections.
