Nah no need to be worried yet.
Some geckos don't eat a ton of CGD, and it's typical for new owners to not realize whether a gecko is eating or not. Looking for poop is the best way to see if they are eating.
A week is the minimum to wait before any unnecessary handling.
Temps sound good too
As for being on the ground, two of my geckos really seem to prefer it. My biggest female sleeps under the paper towels. My biggest male just likes to hide under some big leafed vines that are close to the ground. The other two definitely are climbers for the most part. A 10 gallon, imo, might be a tad small for an adult gecko(some would disagree though so don't worry! 10 gal. per adult is what some quote as the rule of thumb for housing adults), I like to give them a bit more room and a bit more choice in hiding places.
Personally I love glass exo terras at 24'' tall, ground space variable depending on whether housing geckos alone or with others.
