To #3: Yes. No. Sorta. I agree with others here who regard it as a sort-of-fictionalized account of how the Muppets started in show biz. Think of it as a highly simplified, some-parts-played-for-laughs version of the truth...which then does mean that Muppet Babies never actually happened. But eh, like Ed said, nothing is really canon except the characters' personalities!
I think once I saw the movie again as an adolescent/adult, it was more of a "this is the Hollywood version of how they met" and not the "this is how the Muppets met" that I recalled from seeing it as a toddler/kid.
The thought occurred to me again as an adult when I realized that, if Muppet wiki is true and that Scooter was about 14 when he started working on the Muppet Show, there could be no way he was the Mayhem's band manager, unless his uncle managed to get him that job too.
To #4: The original Muppet Theatre, where the show was filmed, was portrayed IN the show (though never directly identified as such) as being somewhere in NYC. (Note the number of New Yawkers or Joisey guys, such as Rizzo, but a few others had similar accents, and a number of jokes revolved around NYC locations -- I seem to recall Statler and Waldorf having a few of those.) Now, this could just as easily have been the Muppets on a SET of an old vaudeville house in NYC ACTUALLY located in LA...but why complicate things? I personally think they went to Hollywood,got into films, but then wound up taking over the run-down theatre in NY as a fallback...but again, do whatever you want with the premise.
Huh. Really? I've actually never noticed, other than Rizzo. Now, with that said, I grew up with movies first and then was introduced to the TV show (once I was old enough to watch and it's probably the only time I've been right that a character from one show got a spinoff on another show).
Was it always like that or did that happen around the time that Rizzo was introduced? I had always assumed that they had met Rizzo while in NYC for MTM, of course only discovering recently (like this month) that Rizzo was actually on the show (the same is true for Uncle Deadly, who I thought was introduced like Walter was)
To #6: If we accept that the shot of the house from the front gate IS the house, then yes...two-story with an attic, a classic Storybook Bungalow from the looks of it. Remember, we only saw a couple of rooms INSIDE K&P's house in the movie.
I went with Spanish style and I think that was a case of art imitating my art. From the distance when Gary, Mary, and Walter are looking through the gate, it look around one or two story, I thought, hence why I couldn't decipher. With that said, Spanish housing kinda does make sense, especially on the West coast where we have a lot of Native American and Mexican influence in terms of housing and street naming (I'm from Arizona), so that made sense to me.
Play with all of it. Some of us accept the Muppet Boarding House, some prefer NYC and the theatre, some like the crew in LA making movies nonstop. Do what you want -- the Muppets themselves always do!

You'll be happy to know that, not only did I work on the thing I wanted to first post here, but I managed to get started on something else I wanted to post. The second thing was kinda a fluke because it was a sad passage for another wise happy story and then I said, hey. This would be perfect for that sad story I have. Brilliant!
Thanks everyone fer yer help!
