I've got long, average width feet. I have seen more than once that when boot lasts are stated, they are stated at size 26.5, and increase by 2mm per size. Does that mean that a boot listed at 98 last, becomes a 102 at size 30.5? Is this standard for all boot makers? If so, I would have to shop boots with a listed width of 96/98. A boot with a last that narrow is usually a high end expert or race boot - not my style of skiing. I would like to go to a boot fitting with a little basic knowledge. So, if I measure my foot at the widest point in the forefoot, will that give me an indication of last I should be targeting? I know that there are other factors. Not trying to second guess the experts. I just like to know a little more when I'm making a significant investment.

After years of reading about boots I don't think there is much that is standard for all boot makers. There are general rules that apply, as you say.
Yes, last widths are quoted for size 26 boots. Yes, as a general rule the last will increase 2mm for each size up (except for Scarpa, whose boots change sizes based on the half size). A 98mm last boot in size 30.5 will be four sizes up from 98mm, so you can expect them to be (sort of) 106mm in that size. The length of the boot cavity for a certain size can vary between manufacturers and across models within a manufacturer's lineup. Forward lean, canting, zeppa angle, stance/balance alignment, calf shims ... there are all sorts of variables at play.
I've been working with new boots this season - 100mm last Tecnicas. My bare foot measures 116mm wide. I'm in a 29.5 boot which, using the above rule of thumb, means a 106mm last. After five days I've decided I need to punch the shells at the first metatarsal. After a couple of hours they're 'squishing' my feet (a technical term). I can ski them, but they hurt. On the other hand I don't expect I need them punched out to reflect the full measured width of my feet. That would be far too much. They're almost great now, they just need a little punch to stop the squishing. A 4mm or 5mm bump should be enough.
There are a few good general notes on boot fitting around if you search. I'll send you some notes I have jotted down as a PM.
Boot fitting is the most complicated area when it comes to ski gear. The very best advice is to choose a reputable boot fitter and put your full faith in their abilities.
Best of luck.

Don't get too hung up on the measurements (neither your actual or the boot's stated). There is very little standardization (sp?) and forefoot width is very easy to expand. For example I have a wider than average foot and wear an 11.5 street shoe. I am in a 9.5 Salomon XMAX 130 with a stated forefoot width of 98MM and they are roomy (no, they have not been baked or punched). A little bit of homework can be a good thing but as Sinbad said put yourself in the hands of a good fitter and go from there. Otherwise you may drive yourself nuts trying to figure it out at your computer.
