It sounds like you've just got yourself a little one. It also sounds like you weren't given much info when you brought this guy home. Keep in mind when you get a new pet there may be more that goes Into them than you think!
Lights- heat lamp spot light basking bulb. You need one that get your basking zone to at least 100.f 103.f is preferred.
UVB/UVA- like the above poster said needs to run length of tank. Honestly I think a 10.0 is The best.
I think a 20g is minimum for a juvenile. They need space to thermoregulate and bask. I think The overall 10g will be a bit too small and you'll find that your cage will be a bit too hot.
You need calcium. 2 kinds. One is pure calcium- grab a bottle of tums fruity flavored is fine and crush up the tablets. This is pure calcium and you will use it half the time.
Calcium with d3. Make sure it is phosphorus free! You will use this in conjunction with the tums.
Now babies need to eat daily. You'll be using the calcium d3 only on 3 feedings a week. The other feedings you need to dust with the tums. Also putting tums on the fresh veggies.
Fresh veggies-
My adults and babies are raised on a daily Salad of:
Collard greens, mustard greens, spring mix, parsley, carrots, corn, peas,endive, dandelion greens. Sometimes a little fruit like red and black rasberries, or mango.
Substrate-
Don't use sand with a baby. I use a sand mix with adults. But never with the babies. And really don't get calcium sand. Dangerous stuff! Actually play sand isn't bad. As Long as it doesn't have silicone crystals In it. The silicone is actually what causes impactions. But sand should never be used for any animal under 1 year. And it depends on your animal as well. Aggressive feeders that dive to grab their food I dont give them sand at all. Unless you are very experienced I never suggest for folks to use any type of sand. Impaction is a combination of poor husbandry and bad substrate. Just skip sand all together for this guy.
Keep a youngin on paper towel. Easy to clean and safe.
Hope this all helps
