Just curious, but what's the temp of the water and basking area, how far away is that UVB (?) light from the turtle when he's basking, and is there any plastic covering over it?
Some greenery would give him privacy and a place to rest. Make sure any plastic plant you buy doesn't have wires it (or take them out--they'll rust in the water).
The only heaters I've seen at the Walmart near me are very small--only 25 watts. You want a 50 or a 75 watt heater for the 10-gallon (if you get a 100-watt one you can use it if you upgrade to a 20-gallon).
