nai13,
The 10 gallon won't last for long. You'd want to upgrade to the biggest tank you
can afford. I think 100 gallon would be perfect, because that'll last for the rest of
your turtle's normal life. That will also save you from buying another tank in
between.
I dislike substrate because that traps debris and makes tank maintenance a hassle.
Besides, if the gravel is small enough for the turtle to swallow, that will be a bad
thing. I'd recommend removing the gravel.
Water temperature is a little high at 81°F. If you can, lower the temp to upper
70s, since your turtle is still a hatchling. Basking temperature should be around
higher 80s to 90°F (about 10°F higher than water temp to entice basking). Your
turtle will find the basking area itself when it gets accustomed to the tank.
Refrain from touching your turtle too much so it can get accustomed to the tank
quicker.
Other than regular light bulb for heating (60W is sufficient), you'd need a UVB
bulb. The common type used is Exo Terra Reptiglo 5.0 26W or its equivalent.
Follow the directions so that your turtle's eyes don't get irritated while basking.
As for the name, one of Novroz's turtle here is named Kame. Honu is an
interesting name; it doesn't sound gender specific, perfect for a hatchling
