Those photos look good - they take me back to the time when I was there 18mths ago. You can get in a lot of museums/ruins for your money. Coricancha museum tells you about the history. Also at the various ruins a local is only too happy to give you a history lesson for a couple of soles.
If you like your authentic peruvian markets try chinchurro (can't remember the spelling).
Also, Ollantaytambo village (half way to Machu Picchu) is quaint and buzzing. My recollection of that was us going to a petrol station and seeing a llama in the queue of cars waiting to take a drink out of one of the owners big vats !
Re biking, it'd be difficult to get in much road cycling as their use of the word "road" (carretera) is very open to description - you wouldn't want to use your prized Pinarello round there ! Mountain bike all the way !
It'll be great fun though. I did a ride on a mtb - great fun. If it's downhill, they'll probably take you up really high (above 4,000m) and then let you roll back down toward sacred valley (below 2,000m) - the contrast in flora is very impressive.
Palace fan in Peru ! Things seem so much more glamorous when you're so far away Btw, that's the best way to get chatting to a Peruvian (in fact any S. American) when you're over there - football. You might even want to take up the sport - forget cycling !
Que lo pase bien !
