1. Boiling a portion of the mash liquor, say a gallon or so of the first runnings. I wasn't sure I saw a consensus about whether or not this is a good idea or not. Does it work? What are the cons to this? And how long and how much do you boil?
While this does work, I'm more in favor of the apparently excessive three hour boil. Just ask anyone who has tasted my beers.
2. A regular decocotion mash schedule for this. Well, does it work, how much and how often (how many steps in the decocotion mash schedule, single, double, etc.)
A decoction is not required, and is not traditional, but IMHO it really contributes to the flavor in this style. Either a single or a double. Keep in mind that this will extend your mash time which is a good thing, especially if you are on the north side of 1.120 og
3. Extra long boil, I've read somewhere where some do a three hour boil. Yikes? I'm sure an hour long boil isn't going to cut it but do you really need to do that long of a boil? How about 90 minutes or 120 maybe? Do you need to add water to the kettle or should you sparge with more water if using this "trick"
I usually sparge longer to get the OG that I am shooting for and often am boiling in two pots 9-10 gallons to get 5, I like my OG around 1.130 in this style. IMHO it is the single biggest factor that contributes to the flavor of this brew.
4. Can you use any of these tricks in conjunction with another one? If I boil for two hours plus the first two gallons of the first runnings will this add too much maltiness for example or is it overkill or is there a point of diminishing returns where I might not be hurting myself per se but its more work for little to no influence on the final product?
Absolutely, that is the realm of the homebrewer, to experiment and do something different. As for me I NEVER break ANY of the established RULES,

5. Where does the Wee come from anyway?
The Scottish are a sarcastic bunch, eh!
