Preparing a car for sun and heat

I have an '02 Ford Taurus with black leather interior and black exterior that I need to prep for usage in South Texas.

I'm just a little worried because some of the products are not good for the car. I would like to put in some window tint and get it professionaly done but I don't know which brand is the best. I'm looking for window tint that won't fade or bubble in a reasonable amount of time. I prefer the silver window tint. I don't like window tint that fades to that purple color. I don't like the color purple and I would not want it on my car.

As for the exterior, any ideas on what type of car wax for all of that intense sun shine beating down on the car? In direct sunlight the black exterior paint gets too hot to the touch. I'm afraid it will become burning hot down in South TX. Is there anything I can do to prevent paint fade; rather than just waiting for it to fade so I can repaint it metallic silver?

I already have a windshield shade.

The leather interior has never been treated with any type of product. I'm worried that certain products might damage the material. As for the cloth floors-rugs, are they made of cotton or is it a petroleum based synthetic stuff?

The dashboard has never been treated with anything either. I need to wipe the dust off of it and apply something that won't reflect the sun into my eyes. Are those dashboard covers worth it? The problem is it will block the airbag on the front pbuttengers side.

Are those vynil nose covers a good idea in south TX?

What about the bug deflectors, are they worth it. Do they waste gas? How effective?

Will I be needing deer wistles? Are they held on by adhesive?

Keep in mind that this is a NorCal car and so none of the above was ever necessary. In fact I only use the windshield shade when parked about 3 days out of the year during the summer months. It's used more as an umbrella rather than what it's really ment for.

Is there any way I can get one of those remote ignition starters? I figured it would be better to start the car from inside the house and wait 10 minutes for the A-C to cool down the interior so that the leather won't be scalding hot. How do those electronic gagets install and how much? Also which is the best brand to get which is the least tempromental?

Thank you in Advance.
