During the day if your temps are in the mid 80's you will not need a hot spot however if temps fall under 80 at nigh I recommend to provide a hot spot.

Proper heat are very important not only for overall health (you do not want your temps to fall below 75) but also to facilitate proper digestion (in that case I would recommend to have your temps at 80 min at night.)

For the rest there are caresheets and tons of threads on how to properly setup your enclosure.
