Cost to replace is the amount of the new sensor ($35-$40 each at Rock Auto) and ever how much your local tire dealer charges to replace them (call around and see who's cheaper). May as well go ahead and change all 4 of them though, since they are all the same age. Would suck to get one changed only to have to make a return trip to the tire shop to get another one changed a month or so later.

These #s are for GMT900 vehicles (I think that included the '13 MY) 37 lb-ft on the exhaust manifold to CC 70 lb-ft on transmission support to frame 30 lb-ft on transmission mount to support
100000 mile maintenance schedule recommends replacing spark plugs and inspecting wires. Go with OEM plugs/wires. The plugs come pre-gapped and you can get them at any auto supply stores (when I changed them I got them at O'Rielly's) or order from any online retailer (RockAuto, Amazon, Ebay, etc). Same thing with wires. Fluid and filter changes Inspect/replace drive belt
According to Crutchfield, it would be the Pioneer AVH-211EX According to Lifewire (best overall) it would be the Pioneer AVH-4200NEX, best budget would be the DEH-X6900BT According to Wirerealm, it would be the DEX-P99RS All depends on how much you have to spend, what features you want, how serious you are about the quality of the sound, etc
If you ask 10 people, you'll get 10 different answers. It all depends on what you are wanting out of the radio. Competition quality? More features? Best value? Brand? Look around in the Audio, Electronics, OnStar, MyLink, Intellilink & SiriusXM forum and see what all is being used https://www.gm-trucks.com/forums/forum/28-audio-electronics-onstar-mylink-intellilink-siriusxm/

I will also add, this was my first time really driving a newer, non-ragged out diesel (drove several while working construction, but they were older fleet trucks that were nearly dead). My dad bought this truck new in '11 and mainly used it to tow our 5000# Kubota tractor. I had driven it a couple of times around town not too long after he got it, but never really felt the real power of it. First time I towed the tractor, on our 25' gooseneck trailer with a 6' disk, bush hog, and seed spreader, the power of these trucks really showed out....I looked at the speedometer, accelerator pedal barely pressed, and was doing 70 mph going uphill. And the truck felt like it never even knew that it was towing right at 10000#.
The 11s have the DEF...might want to think about a delete and tune (especially if it's out of warranty anyway). I inherited my dad's this past March. DEF heater and NOx sensor went out. Dealer told me the NOx sensors were on backorder and didn't know when they would be back in stock (could not find them online either). Got the "Speed Limited to 55 mph" warning on my way home from work one day. Headed to a local diesel shop and as I was pulling in, I got the "Speed Limited to 5 mph". Talked with the guy that runs the shop and wound up with a delete and tune.
People "upgrade" their vehicles all the time, to make them look like something they aren't (buddy of mine had a Monte Carlo LS back in the early 90s but wanted an SS...he found a wrecked SS and bought the front clip, truck lid, etc and put them on his LS. Had it painted, SS decals put on, and no one ever knew). Previous owner could have purchased it, slapped some Z71 stickers on it, replaced the engine and interior, etc.
Window regulator...$40-$50 fix (order from Amazon) and about 45 minutes One of the back windows in my wife's 05 Tahoe did pretty much the same thing. Replaced the window regulator and it's been fine ever since
Can't help with the other parts, but regarding the quick disconnects at the heater core...go with GM instead of the Dorman. I used a Dorman QD on my wife's Tahoe and wound up having to replace it again in less than a year. The GM QD I used is still going strong after 2 years.
