Wow, that's quite an acrobatic BP you have there. Don't sweat the shed too much. If you need to help him get the rest off, wet a pillow case, and let him crawl around in it for about an hour. Should help him rub off any remaining shed. Works especially well for the nose and head area.
Keep your humidity right in his new enclosure, and you won't have any trouble with his next shed. Sounds like you have a very good set up so far.
