Hi
Nice 1GHz O/C you have achieved.
The voltages for the Motherboard are all OK and although the Voltage for the CPU is at the top end, I don't think you will have too many issues running 24/7 as your temperatures are really good.
Overclocking, by its very nature, can shorten the life expectancy of the components and this is always something you need to bear in mind. The faster and harder you push your PC the shorter life span it may have and it is always a compromise between the two. As I mentioned before I decided to pull my own system back to a modest 3.8GHz on the CPU, the RAM running at 1333MHz because of the known issues with running RAM at a higher speed on AM3 CPU's, with all other settings left at default. This is a compromise between extra speed or PC longevity and I decided I would like my parts to last as long as possible.
