Question accessibility
NVDA as Ron suggested is probably your best option for testing. The latest versions of SL will work with screen readers in preview mode which is really useful for testing as you no longer have to publish the course constantly to do your testing. You just need to switch on the global option for it (sorry I can't remember where it is).
You may have to do some config on NVDA to get it to behave how you want, but out of the box it should allow you to test the basics.
As the focus order screen shows all the layers and content together I just visualise them as their own individual groups and place things in the correct order according to their group. I don't think the groups position within the focus order makes a difference though, just the order for that group of elements on the layer (hope that makes sense).
