I think you have it pretty much covered,my 10 yr old Chevy with more than twice the mileage is in great shape.
This is what I had done at 100000 miles,the only thing I would check is the rubber brake hoses,I had mine replaced,they tend to deteriorate from the inside and you don't want to have them to fail, they may look fine on the outside,they run about $85 a set.
If you have a Chevy truck dealer nearby I would have them do it or if you have a trusted mechanic that would be the way to go.
My alignment is good too,when I had it checked at 90000 they said that everything was in great shape,it had been maintained very well and they found very little wear.
