In November my wife and I are headed to the aforementioned destinations. [...] I read that nothing over 200mm is allowed at Machu Picchu unless you pay $300 as a pro photographer, which I certainly am not.
That's a great trip! I was there 2 years ago with NatHab. I'm sure you'll have a blast. If you're flying into Cuzco and hiking around there a bit before heading to Machu Picchu, the altitude on site will seem like a breeze.
I can't say for sure re the 'pro' photography fee, as my 70-200/2.8 was the longest lens I brought. That said, nobody said anything about it, nor came up to check it out enough to determine the focal length, so I doubt that's true in practice, even if it is official policy. The place wasn't mobbed by photographers, though there were definitely a few people with tripods who weren't getting hassled by the park staff. Nor were the kids smoking pot; it's pretty laid-back.
If you want to climb Huayna Picchu to get a good view of the site from above, you'll need a separate pass, and there are limited numbers of them available, so inquire before you get there or you may miss out as I did.
You'll definitely want to get up early (5:30 or so) at least one day to take the first bus up from Aguas Calientes. Check what time that's going to be, since it varies (and be prepared for the truth to be something other than what you're told; bring a book or something to read in line). Then when you get there, head up and left to the Inca Bridge. It's maybe a 45 minute hike, but totally worth it. When we were there, we had the place to ourselves for about 30-40 minutes before a tour group got in. The morning fog rolled in and out at least twice while we were there.
The hike around the opposite side, to the Sun Gate, is worthwhile too but was more crowded and less appealing. Though we were there later in the day; it could be it's just as magical in the morning hours.
On FF, 24mm was wide enough for me - I stitched anything I wanted wider than that. But I could definitely see wanting a wider lens. There are a few details that you might want something longer than 200mm for, but as an amateur, it's hard to justify schlepping around something that big for just a few shots. More to the point, bring a hat, sun shirt, good hiking boots, or at least comfortable shoes with good tread, and good-sized water bottle. You'll be sweating hiking around the site. And don't look out the windows on the bus ride if you have a healthy fear of falling off the mountain.
