This is something another user put together on how to build a good salad.
That heat lamp should be good for your tank, but it really is trial and error dialing in the temps. As Mango mentioned you want digital probe thermometers. Put the probe on the basking surface and wait 10 min. You want that temp to be around 110F while a baby and down to around 100F for adult.
For UVB, a ZooMed Retisun T5 hood with a 10.0 bulb (it comes with a 5.0; save that as a backup) or Arcadia ProT5 with a 12% bulb are top recommendations. I would go with a 24" for your tank, and if you ever upgrade to a larger size enclosure that size will be good up to a 48x24x24. Placement of the light will depend on if you have a screen top, how wide the holes are, and whether you will be placing it on top of the screen or underneath inside the tank.
Hope this helps!
