No problem, glad I can help. Let's see, have you gotten your hands on a few care sheets and or a book? (crestedgecko .com is a good start)
I guess the list would be: enclosure, substrate (papertowels is fine), plants, a hide (tupperware or plastic hides, we have one intended for use with hamsters, but it is perfect), a water bowl, a food bowl, crested gecko diet (CGD), organic baby food (like bananas, apricots, or peaches, never any citrus) - we found that little cresteds don't always take to straight CGD, but mixing with half and half baby food temps them. (Now our full grown only wants straight CGD, weird huh?) Crickets until s/he is full grown- which may mean a cricket keeper, gut load/cricket food (we like "cricket yummies"
, and of course calcium/vitamin dust (those designed for leopard geckos are usually recommend). What am I forgetting? A thermometer and a hygrometer and spray bottle... and a gecko!
Oh, if you have hard water like we do, you may want to consider bottled water for misting if you still want to see in the enclosure after a few days... we learned that the hard way! That's what I can think of off the top of my head for a checklist. Knowing a good herp vet in the area is nice, hopefully you'll never need it.
I wish you the best of luck, cresties are very fun and funny, even if they can be a pain to clean up after sometimes! All the hoping and flopping and their funny expressions. Please ask anything else I've forgotten.
