I think you scored big on this one. Many vehicles with that mileage (depending on maintenance history) would need much of what you're planning to do. When I bought mine 3 1/2 years ago, with 48K on it, I went through everything, just so I'd know what and how things were done. It's been virtually trouble free since then, with only normal wear and tear items needing repair/replacement.
Ball joints, struts, and tune up is all easy stuff. I would recommend doing a complete (and then some) 90-100K service on it...replace all fluids/oils and filters (trans/diffs/Xfer case/radiator), serpentine belt, MAP Sensor, clean the throttle body (and get a catch can), check the spark plug wire resistance (if bad, get Taylor Shorties), EGR Valve, O2 Sensors, etc. For ball joints, Moog are good, for shocks, many of us use Bilsteins (I love them), and I use NGK LZTR4A-11 (Stock No. 5306) spark plugs (it takes 16 plugs) in both my Hemi vehicles. Any good copper core (a must) plugs will work though. If you do all this yourself, you should be able to do everything for ~$1000-1500, and you should have a pretty good and reliable vehicle. Also, use a good synthetic engine oil.....must be 5W-20 for the MDS to work properly. All oils/fluids/filters will run over $300. The good thing too is that you don't have to do it all immediately. Just make a list, prioritize it and pick away at them. Let us know how it goes, and welcome to the forum.
