Also, there was no insulation or vapor barrier under the house - electric bill was $800 for December/January.

I will likely keep the carpeting in the bedrooms but is there something I can do to further protect them like laying down a vapor barrier between the carpet and the carpet pad?

There are defenses to liability for property owners whose property is impacted by contaminated groundwater from an off-site source so long as you exercise what is known as "reasonable care". (2) since you will be using this for self-storage, this will be considered a commercial, not residential use, and many states have less stringent standards for commercial properties since people are not occupying the property 24/7. (3) If the levels in the groundwater would pose a risk of vapor intrusion (vapors migrating up from groundwater), you can install a passive sub-slab depressurization system (ssds) that acts like a radon system-capturing the vapors before they can get into the structures.(4) if soil is contaminated and you plan to pave the surface, this will generally be sufficient remedy if the soil contamination is at depth.

New roof and a company is coming in to install a radon mitigation system so the basement is getting a vapor barrier installed all before I even close on the house.

You could maybe cut that cost by making one of those lights a motion detector, but I think that a full time florescent bulb is going to be cheaper to run than turning an incandescent or mercury vapor off and on.I've got a dusk to dawn florescent security light that is 14 watts.

If you don't really know anything about construction,I'd suggest you begin my learning each element or part of a house, from the vapor barrier at the foundation to the ridge of the roof.

Some sort of vapor barrier and/or insulation?  

WEAR A RESPIRATOR WITH ORGANIC VAPOR CARTRIDGES.The new stuff will usually blend well enough into the old stuff to pass muster, especially on a parquet floor with all the variations in shading.

Since the AC condenser acutally condenses the air pulling the water vapor out of the air and area's like Nick's is said to be dry heat.
