Yes, it's fine. Seen a lot of people running it at 1.7-1.10 and some higher also. So you should be just fine at that NB voltage.

Don't think your board is flashable to the Rampage Formula being a p35, but the P5E to Rampage thread by ericeod is really worth looking at for ASUS mobo voltages, OCing etc: http://www.overclock.net/intel-mothe...hread-155.html

You really shoudnt need any more PLL yet. I would strongly recommend leaving that at the lowest setting.
You might benefit from extra FSB term. Since you have a 65nm chip you can crank the FSB term all the way to 1.5v without worrying about damaging the chip. You will have to experiment with this a little.
It is possible you might just have a poor overclocking CPU. I know I had to push the voltages on my E6600 much higher than others, and thats just the way it is sometimes. These are the settings I needed in BIOS. Different CPU and mobo, but it may help.
vCore 1.525v
VTT, FSB term. 1.55v
NB 1.4v
HT 1.2v
SB 1.5v

Agreed on the CPU PLL voltage at this stage. Upping the FSB Termination might well be beneficial; esp since you don't seem to have touched it and it may be terminating your OC. As mentioned, your FSB specs would be worth knowing.
Also, you might try lowering your RAM frequency to 800MHz. Sometimes this gives a much better OC.
