Hi Bethesource,
We typically recommend using the BFST on bare skin, with about two fingers space between the wrap and your skin.
As for exercises or stretches, I don't have any specific stretches to recommend, but I do advise paying close attention to any pain signals your body may send you during exercises or stretching. Certain exercises or stretches can actually aggravate your injury further, so if you do an activity that causes pain or discomfort, I suggest listening to the pain and doing it less or not doing it at all.
I am not familiar with Xeroshoes, but after seeing their website, their shoes sound like they promote a healthier, more natural way of walking, so if those work for you - awesome!
I can tell you've definitely done your research and that you're very motivated to heal. Consistent use of the BFST will help to heal soft tissue injuries, so you are on the right track!
