Question 1: Why does CPU-Z show 1.24v when I set in BIOS 1.2525 or so? I've noticed CPU-Z usually shows around .1v less than what I specify.
Question 2: Is it okay if my first two cores are about 5-7 degrees hotter than my second two cores? I'm hitting around 73 degrees on first two cores and around 67 degrees on second two cores when running at 4GHz and at load using prime95.
Thanks.

It's a natural behavior of electricity under resistance. So you will see less in cpuz than set in bios. You will see additional loss as the load increases and the resistance becomes greater.
It's pretty normal to see different temps I wouldn't worry about it. However 73c is kinda warm for any processor long term.

For comparison purposes, without disabling speedstep, HT or anything else.....I am at BCLK 176 @ 3.7 Ghz w/1.2 volts CPU and 1.56 DRAM. RealTemp Cores max recorded are 66/63/63/63 on a Prolimatech Megashadow w/ twin 1500 rpm Enermax Magma fans @ 83% speed (1250 rpm)
Disabling Speedstep and HT at 4.2 Ghz but that's just for fun and experimentation. temps at that setting are 71, 69, 68, 67

My Comparison,
I7 920 w/ Asus P6T Deluxe
I am at BCLK 191.89 X 21.0 = 4030 W/ 1.184VCORE. Temps @ 52(3) @ load, and @ idle, 35's. I use the Corsair H50 CPU Cooler.

1. It is due to the overvoltage protection by Intel which is related to the drooping voltage
2. There is a 5C difference between my 1st core and the rest cores. It is due to the bad temperature sensor which is very common.
