No problem, happy to help. There's quite a few board members up in your area of the country, so maybe one of them will see this thread and can direct you to a good 4x4 shop in your area. Other than that, many people use the internet and online retailers to buy stuff for thier Explorers. And I think you'll find that many people here do much of thier own work, body lifts and suspension lifts included.
About the width, I'm sure once you lift it, you're gonna wanna throw some big, wide meats on it. As long as you understand that the truck is lifted, and drive it accordingly, you won't feel any less stable than you did stock. (From other board members, my truck is still stock height). Aftermarket wheels are also popular after a lift, but as to what back spacing will allow you to have a wider stance, but not force the big tires to rub too bad, I don't know. Someone with more direct experience than I will have to help with that. I'd suggest a search.
