For household light, use whatever wattage gets the basking area temp in the 88-90F range. The bulb should not be so close that your turtle can touch it.
Many people here seem to use Repti-Glo bulbs for UVB lights. If I were to use a conventional UVB light, I'd use a Reptisun tube flourescent, probably a 5.0.
If your tank is around 50 gallons, I'd use a mercury vapor bulb (MVB) that would provide both UVB/UVA and heat. (Regular UVB lights also provide UVA rays, but you do need that heat bulb.)
