I am soon going to be a first time tarantula keeper...?

[fuzzy]

You can get a 10 gallon aquarium it's not that big of a difference in price rage. Or you can be cheap get a big 8 dollar plastic tub at Walmart and poke holes on the side for air or on top. Don't put bark or sharp bark for the substrate that could puncture the Tarantula also Tarantulas are not dessert animals therefor sand is not needed so use Eco Earth also you've a hideout that's good and you need some fake leaves you can get a dollar store last but not least a small water bowl. Mealworms or Crickets both depending on what your T likes don't leave uneaten crickets remove them a few hours if not eaten this is what killed my first Tarantula because listening 2 a stupid sales person Petco because they told me dump 4 or 5 crickets in there and leave them in there crickets are very mean animals and will gang. Also your temperature seems a little cold I would say 75 is normal for a T your best bet is 2 go on Tarantula Classified FB and as around also you will pay more for a Female than a Male
