Yeah pretty much. I can't think of any differences really. If you install it and leave it not configured whatever that option is with not configured and then configure it through Reporting Services configuration manager you should be fine with the defaults when it's on your own laptop. A couple of the things I can think of where you could get tripped up would be on some of the pages with the defaults, you have some warning thing towards that top of the page that says whatever is not configured. Those are really just a matter of clicking the Apply button on the bottom. It's kind of like confirming you want those defaults. I think it does that on both of the URL configuration pages - web service and report manager urls. The other thing I've seen people get confused with (it's not just you) is when you get to the Database page. So on a new install where you leave it to be configured through Reporting Services Configuration Manager, on the Database page select Change Database. And then some other window will pop up and you point to the SQL Server instance where you want the ReportServer and ReportServerTemp databases installed.
And then if something wasn't set right in that process, you should get an error in the Reporting Services trace logs.
