How did you wash your clothes? By hand or were there places to wash them?
A few refugios had washing machines, but I washed by hand. The one time I didn't have coins. To hand wash, put my clothes at my feet into the shower and then hand wash them later. I hang them on my pack and they dry quickly.
Did you carry a phone or electronic device to respond to emails or post journals? If so, which one?
During the Pyrenees I used the Acer Aspire One netbook, which was complete overkill. I had to bring it with me anyway, but in your case, I would recommend something smaller and lighter. I'd go with a smart phone, like the iPhone, but if you'll do a lot of typing, then consider phone that has a dedicated QWERTY keyboard.
Does mobile coverage work in the Pyrenees? Specifically, I´m wondering about Orange.
I'm not sure since I didn't have a phone, but I'd bet that 80% of the Pyrenees is covered. I'd get a SIM card from a Spanish mobile carrier (I can't remember if Orange is French or Spanish). The Spanish side of the Pyrenees is nicer than French. Also, look at Andorra - they're in between and maybe can offer something that doesn't have roaming charges between the 3 countries.
I was talking to a couple guys from Barcelona the other day who claimed that the refugios were not staffed and/or did not serve food in Spain. I thought this unlikely, could you shed some light on this?
They're 2/3 right. There are three types of refugios:
1. "guardados" (guarded): "full-service" refugios. Beds, meals, showers, flushing toilets, the works. No camping allowed next to it.
2. libre (free): nice fully enclosed self-service huts. Beds are there, but they don't always have mattresses. They have no meals or showers.
3. Cabinas (cabins/shacks): barebones, rustic shelters. They're like AT shelters, with four walls + roof.
There's roughly equal proportions of each type of shelter. The maps will indicate what type of shelter is in each spot. My favorite are the libre ones. I almost always had them to myself, but in the high season they may be full since many like them.
Good luck!
