|Those a a whole bunch of questions so i will answer them one after another in the order you asked.|
your temps are fine. Your processor specs are as follows;
Max temp-70C, Thermal design Power-89W
Max core amperage-57.4A
Safe for not only a dual core but most processors.
A safe temp for a chipset depends on the type of chipset in question.
32 C for a chipset(any chipset) is also fine,chipsets in essence can actually get very hot and yes overheating a chipset can freeze your system
The higher the overclock the more heat dessipated from the chipset. Needless to say, keeping a good temp for your chipset is essential for a stable overclock
