I really hate to knock the dealer BUT it sounds bad to me.
First ask them for the EXACT trouble code that came up. Simply saying it had a misfire could mean a lot of different codes. If it was a random misfire in all cylinders that would mean a different solution than misfire detected in cylinder number 3. Even then a set of plugs, plug wires, cap and rotor for the 4.3 is under 200 bucks. Throw in a top end cleaning and injector cleaning and you might kill $400.00 including labor.
As for the broken mounts, I have owned 7 S-Series Blazers and have seen one broken mount! I've replaced one on a customer owned vehicle, they don't fail that much.
Hub being bad on a Blazer at 81K, Very possible, BUT for you to drive it in and not notice it before they did work on it? Not likely, they don't usually fail that fast The usual failure starts with a hum that gets louder and changes note as you turn. I have seen them go 5K miles making noise and never had brake related shaking from it. I would surmise the brake problem was a result of rust on the rotors. Not much to do but turn them and throw on a set of pads. The cracked radiator? Not sure, that isn't a common thing. Without seeing it I can't say.
The latest problem could be caused by the "tune up" they did. It could also be unrelated.
If it was me I would take it to a different BUT trustworthy independent shop (ask around and get recommendations) and have them look it over and see what they say.
