I work at petsmart and i sold a small beardie to a customer a month or two ago. Sadly his situation changed so he asked if i could personally take him since the store can't accept it back since its been a while.
So I've been reading everyone else's posts and I've been on beardeddragon.org for a while but I still have a few questions.

First off, let me list what i do have and what i know so far.
it's a 20 gallon long tank
the beardie is only a few months old. the body is about 4.25 inches from head to vent.
water dish
this little leaf dish...thing.
a rather large half log (i know you're all going to eat me alive for this)
one of those reptile hammocks
a basking...ornament.
carpet for bedding (and i have some for my leopard gecko and i know its a pain to clean so i'd like to change it)

i've been checking the temps frequently with my temp gun (RBI 205L)
the warm side is about 95 on the ground and 115 at the very top of the ornament (but i haven't seen him up that high)
84-86 on the cool side.
its a 75 watt bulb
and i have the UV lighting.

i can get pictures up within a few days.

all i'm really wondering is can i change the bedding to tile?
does he need a calcium dish like my leopard gecko?
he's eating small crickets right now and i also bought some small mealies.
i'll be shopping for his greens and such later on.

and how often do i have to worry about clipping his nails?

Feel free to ask anything, add any input, and thank you in advance
