This is what I started with. First step was to move aside all the fluffly insulation, and peel back the rolled insulation. This wasn't all that difficult but I'm a little over 6' tall so it was a tight squeeze everywhere up here. To get to the corners I laid down plywood planks to lay on. Thankfully the weather was cool outside for this entire project so I wasn't baking in the attic. I wore a thick hoodie (with the hood always up to protect my head from the nails coming through the roof. Saved me some pain {and tetanus!} a couple of times) and jeans along with gloves to minimize skin contact with the insulation. Also wore a mask, which was a must. I've worked in the attic a few other times just running some cat6 cables without a mask and I always end up coughing for the next hour.
