On the UVB, it depends..... If you are using the "tube" type fluorescent, you'll need an 18" fluorescent fixture. You can get them cheap at home depot.
A better solution would be to get a "Compact" type fluorescent bulb and place it in a clamp lamp. You'll need a 5.0 UVB (NOT 10.0 or 2.0) and position it a minimum of 12" from the basking area. You can get one here:

You can buy a clamp lamp at the pet store, but they are probably cheaper at the hardware store, like Home Depot or Lowes.
For the UVA (heat) lamp, a regular 60 watt incandescent light bulb will do, also mounted in a clamp lamp, positioned so it will warm the basking area to about 90F.
