The best place to post looking for PCT-specific details would probably be thru-hiker or one of the PCT-specific thru-hiker sites. Some people here have done the whole hike or sections of it, but you will find larger groups of more experienced PCT hikers in those forums.
On the subject of white gas vs. alcohol, if you want to "crank heat" you should look at canister stoves. Canister stoves "crank" more than white gas, and you will be carrying much much less fuel weight *and* stove weight.
The coleman Exponent F1 stove weighs a couple of ounces, it makes 16000 BTU, and it costs $40!
For a remote-fuel stove, consider the MSR Windpro. It is identical to you Simmerlite except that it has no pump: this means it weighs less and is much less likely to fail. Since it burns butane, it can boil more water per ounce of fuel, and it requires no fuel-wasting priming. Yet another bonus is that canister stoves don't clog.
Further, since you will be making hundreds of meals and carrying it thousands of miles, you will appreciate the durability and reliability of the canister stove. White gas stoves are failure-prone just because they have a lot more fine-tolerance parts. For an expedition like that, you should really consider bringing an expedition service kit if you go white gas. A few hundred cycles of assembly, pumping, burning, cooling, and disassembly can wreak havoc on some of the fine seals in a white gas system.
Finally, if you insist on white gas you can always use gasoline as an "emergency fuel" if nothing else can be found. Gasoline contains additives that are bad for your health and will clog your stove more quickly than white gas, but it's better than eating raw pasta!
