... i think HDR's and using high ISO's and tripods should solve some of the problems. ...
No, no, no ... using high ISO aggravates the problem.
At high ISOs the sensor system's tonal range is severely reduced. A single low ISO shot can usually achieve a tonal range equal to a 3 shot HDR at high ISOs and produce better color rendition. This latter attribute is something that HDR, regardless of the number of shots, does nothing to improve.
Use a tripod and a low ISO to achieve the best results, period.
