There you will find all the basics of iguana care. Because despite your claim on being an expert, the basics are not the same for all reptiles. And truly we have not advanced so much in the care of exotic reptiles.
A living vivarium is really not a realistic idea for an iguana. Iguanas are strict herbivores, and our knowledge of what exotic plants they can and cannot safely eat is limited. Even if you determined what could safely be grown, rest assured that your iguana would eat the young plant before it had any chance to flourish.
In addition to Melissa Kaplan's 79 page article, I recommend the following resources as well, most particularly Jen Swofford's Iguana Pages.
http://www.baskingspot.com/iguanas/igbook/ - Jen Swofford's Iguana Pages
http://www.greenigsociety.org/ - The Green Iguana Society
http://www.iguanaden.org/care/index.htm - The Iguana Den
Of course, there are tons of websites regarding iguana care, and I recommend reading as many of them as possible before making the decision and taking on an iguana. They truly are a huge commitment, and while much of the information you read will be repeated elsewhere, you will also pick up new tips, tricks, facts and ideas that will certainly serve you well later on.
