Project Server 2010 - Farm Topology AAM Host Header or Public URL

I am trying to create a traditional 3-tier farm of WFE/App/SQL Servers.

I would like all HTTP requests to go to the WFE. I would also like a friendly URL for the users. I am finding it difficult to get confirmation of the procedure required but believe the steps below would be sufficient:

1. Turn off the Web App service on the App server

2. Create a new web App on the WFE setting the "Public URL" to a URL of choice.

3. Set up DNS for the "Public URL"

Thanks for any advice

Paul

PS this is a straight 2010 farm with Windows Authentication and will not use HTTPS
