As other's have said, it's important to help him remove the shed on his toes as soon as possible. If the shed remains, it can damage your geckos toes/nails.
I would get an extra old Tupperware container, punch some holes in it, line it with paper towels and spray it down with room temperature water. Put your gecko in and close the lid. This creates a humidity chamber that will help to loosen the stuck shed. After about 10 minuets or so, you can take out your gecko and help to remove the shed.
As Jess said, ideal temperatures for this species is about 72-75F so no additional heating is necessary if you're reaching those temperatures. It's the humidity that is especially important as it's what helps your gecko shed properly and so you won't have this issue again.
You'll want to mist your enclosure once in the morning, lightly and once again at night but a little heavier. This should help the humidity for your gecko.
