Hello,
Sounds like you have the bases covered except I would substitute the Ceramic Heat Emitter's with Heat Emitters from Mega Ray and a UV light from them as well.
The heat Emitters from Mega Ray are very unique. Like a Ceramic Heat Emitter, they produce no light and only heat. They are designed however for accidental contact. If your iguana were to accidentally come into contact with it, it would not get burned. Its a great piece of technology. (I use them in my enclosures and have actually grabbed one after having it running for 24 hours. It was hot, but I didn't get burned.

)
The lighting you are considering has VERY low UV output. In 3 months, that light will be producing HALF of the UV that it emits when new which is roughly 35-45 mW/cm2 at 12". You will also need to replace it every six-nine months as the UV coming from it will be so low it will be useless to the iguana.
Now if you purchase a light from Mega Ray, you are looking at approximately 150-200 microwatts (mW/cm2) at 12". That light will push extremely high levels of UV for a year or better!
These are just suggestions of course and what I would do.
