Sounds like a plan to me.
By the way, you can see the changes I've made on my test site:
Login: testuser
Pass: testing124 (yes, 124)
You can view the File Products module (using show-hide with jquery) under My Downloads (on the left). I'm not running any payment gateways or anything, so you can just submit an order and it'll go through, but won't be processed. (So I'd recommend not doing that)
