First off, I apologize if this the wrong forum to ask these kind of questions. Still new to the community and forum navigation is kind of confusing when looking for a place that will actually let me start a thread.
Just have a few questions on my extremely long and extensive overclocking on my i5-2500k.

Right now my hardware that pertains to this is:
i5-2500k@4.5GHz & 1.335 Vcore
Thermaltake Contac 29 heatsink with one fan (waiting on my other fan for push/pull)
750w thermaltake psu
gigabyte z68 mobo with touch bios (all settings related to throttling the cpu when not under heavy load are on auto for the time being)
EVGA GTX 560 Ti (overclocked from 860 to 910 core clock)

1) I have been using OCCT CPU (large data set), and OCCT Linpack for the first tests (cpu@2hrs & linpack@3hrs) and then switching to a 10hr prime95 blend test. If all these pass, I would only imagine that it would be safe to call it a stable clock. Would you? My temps dont even hit 60c with this heatsink by the way.
2) After I can call it stable on the above mentioned overclocking settings (voltages and clock speeds) I will be lowering the voltages, running the tests again, and seeing how much power consumption I can save before it becomes unstable. With lowering the voltages, if I just change the values of my "VCore" will that change the voltages running to the cpu? Sounds like a dumb question, but I have been curious as to if my voltages are actually being changed to the value that I set on the vcore. After I get to the lowest value on the voltage, I will be running the same sets of tests as mentioned in question one.
3) What are your feelings about auto settings for the VCore? I have seen a few opinions, but still haven't came to a conclusion on my own about it. If I set the vcore manually, will this be the constant voltage applied to the cpu? I wouldn't mind having that manual set voltage set as a max, but in times of not having full load, it would be nice to conserve a little power if the manual setting doesn't throttle depending on load.
4) While testing, I have realtemp and cpu-z running. Cpu-z shows what my voltage is when its under max load, could I base my voltage changes on this number that is shown? Or just stick with lowering the voltages by .005 and then testing again?
5) Would this high of a clock potentially bottleneck my 560 Ti? As mentioned I did also overclock my gpu a bit.
6) Would you also say that the clock for my cpu mentioned is a high/good clock?
7) Lastly, how do you feel about leaving all the settings that people say to turn off during overclocking (c1e, eist, c-states etc) on auto? I have definitely disabled the turbo feature as I don't really want to be running my cpu harder than what I set it to at any point even after a successful clock.

I would be very grateful if anyone with good knowlege can help me with all this. To me it seems like a lot to ask, but I figured that I would try and see what kind of help I can get on this. It doesnt take rocket science to up the multiplier on the cpu (which is how I have overclocked, along with vcore changes) but I am still learning a lot on this. A lot more goes into this than overclocking the gpu haha.
I will take any advice and other questions that you may have in order to help me out.
Thanks!
