For the most part, yes, those are the steps.
Since you refer to applications, a few points just to make sure. 1. You would add the new WCF SQL Schemas, Maps and Orchestrations to the same Visual Stuido Solution, perhaps even the same Project. 2. That solution is your Deployment unit and the output of all the Projects go into the same Application in BizTalk Administrator. 3. Once Deployed, yes, configure (bind) new Orchestrations and andy new servcies.
In short, you'd have only one Visual Studio Solution and one Application in BizTalk Administrator.
