Not entirely sure at the moment. Machu Picchu and the Nazca lines for sure. Cajamarca, Lima, Lake Titicaca. I'm interested in landscapes and street photography which I know Peru has in droves. JH, for someone from Peru I'm interested to hear what you think. I have to carry all this stuff. That doesn't bother me as much as taking it and not using it.
EJ, I've heard a few opinions on ditching the MF film side of things; most saying to leave it at home. On the other hand, the resolution and quality of good film is hard to beat. Hasselblads aren't exactly discreet though.
When I was in Peru, we did Cuzco, and a bunch of other villages and ruins in between there and Machu Picchu. I was using a 12-24mm or 17-40mm on one body, and something along the lines of a 24-70 or 100-400mm depending on conditions on the other.
So I guess given your gear, I'd have one body swapping 8mm and 17mm, and the other swapping 24-70mm vs. 70-200mm.
I don't shoot film at all anymore, so the MF stuff is out of my league, but frankly I can't imagine lugging it all around.
P.S. I packed the tiny tripod just for the sunrise at Machu Picchu.
It ended up being a bit of a disappointment, in that when the sun finally gets over the mountains, it is FAR after "sunrise" and we had totally clear sky.... but you got to try! 
City shots in the old sectors and markets are fantastic. You'll take about 300 shots just of doors!
I did not come across any problem with taking photos of people, but I'm shy myself about people photography and not a bold in your face shooter. I did a lot of people shooting with the wonderful 135L in crowds (think your 70-200mm, but damn if it isn't huge and white!) during parades etc. (I think there were parades every weekend!)There are lots of people in Cuzco that want you to take their photo for 1 sole (about .17c last I checked)
And again, in the open air markets etc, people are not at all hesitant of photographers.
As for Altitude, we did not go to the lake, but spent 3 weeks with Cuzco as base camp,... and it is high.
we played around with the altitude pills, but frankly the local "tea" is the best remedy, just be sure not to drink any after 2:00pm or so unless you like to stay up all night!
For me in Cuzco, it was really tough in the beginning, but I was acclimatized to the point of lugging all my gear up the hill to the ruins at the top of the city by week two with no problem. You do just do everything slower though. 
Also, if you start in Cuzco, before Machu Picchu as we did, then Machu Picchu is not even remotely an issue. It's MUCH lower altitude.
