Good news is, you've got a good soil test with enough data to make a lime recommendation. Your stats:
pH: 5.3
Buffer pH: 6.4
Calcium PPM: 798
Magnesium PPM: 179
Ca to Mg ratio: 4.5
I'd aim to hit no more than an 8 on Ca:Mg ratio. So now, lets see how much lime we need to hit an acceptable pH, while minding our Ca:Mg balance. And anyone can do this if they have the charts.

You don't need to go a full point north on pH to get into the strike zone on pH. A full point would require about 2.5 tons/ac. I don't think you need that much. Let's aim for 6.0 to keep it reasonable. So let's call it 1.5-2 tons and start there and see how the crops respond. If you put on 3000 lbs of the lime you spec'd, that would add 900 lbs/ac of calcium, or 450 ppm. You would also be adding 120 lbs/ac magnesium, or 60 ppm. So your new Ca:Mg ratio would become (calcium 798 + 450 = 1248) : (magnesium 179 + 60 = 239) or Ca:Mg would now be (1248 / 239) = 5.2
Now, for gypsum, let's say you commit to a 5 year program of 300 lbs/ac per year of gypsum. That will ultimately be a calcium addition of (1500lbs x .21 = 315 lbs/ac or 157 ppm). That would then get you to a Ca:Mg ratio of 5.8. Still lots of room to add calcium. You might consider hitting up a menards and getting their pelletized lime which is even higher calcium and lower magnesium, and going to 2 tons/ac.
