ST, I bought a 36" fixture and it fits perfectly in a diagonal across the tub. Look at your local fish stores for used fixtures, they may have them.

The only decorations I have in my Bearded's tub is a large river rock for his nails, a Texas holey rock(it's long, flat and white) for basking, and sometimes I will put a piece of wood in there, just for change of pace. Gets him climbing around and wears down those nails.

Mealworms and waxworms are useless feeders. If you want the Beardie to actually grow(and not have parasites from filthy crickets) and not have to spend a ton of money each month on crickets, go with a roach colony. They are SO much cleaner, it's ridiculous. They eat everything the Beardie eats, so even if the Beardie won't eat veggies, you can feed them to the roaches, and in turn, your Beardie gets the nutrients from the veggies. I have Orange-Headed roaches, they are awesome. Don't fly or climb and are chubby little guys.

I'll get a picture of the Bearded's tub so you can see where the lights are mounted. The basking bulb is just a regular 70 watt halogen flood you can get at Walmart or a hardware store. Don't spend your money on those stupid reptile bulbs, they just burn out and cost you $10. I paid maybe $5 per flood bulb and they last forever. I use a ceramic 10" shop lamp that I bought at WalMart and it clamps onto the side of the tub easily. Just direct it down to a flat rock for basking, attach a digital thermometer probe, and you're set.
