Also, be aware that pH changes happen slowly when adding lime. The
agriculture lime is like flour--it works faster, makes a mess, and
you'll need a dust mask. The pellets cost more but more convenient to
use. I use 800 pounds (!) of lime for 18,000 square feet of lawn
every 6 to 12 months (for the past 12 years) and still have a pH of
6.5. My neighbor's (untreated) lawn has a pH of 5.4. The test kits
are worth having for both lawn and garden. Use distilled water for
the tests as tap water is most likely not neutral.

I don't believe it is correct to assume the soil is acidic because pines
grow there. Ours is sandy/alkaline and pines grow fine. Taking a soil
sample from several areas, then taking it to extension service is
recommended here to assess for pH, soil pests, nutrient deficiencies, etc.
Roundup is not a great idea, especially in root zone of plants you want
to keep. It would not be necessary unless the weed growth is too heavy
for the tiller. There is plenty of weed seed in what you will till, so
the Roundup is not "final" anyway.
I wouldn't plant grass up to the fruit trees, because you may damage the
trunks mowing. Is is generally recommended that you mulch (properly,
not right up against trunk). Garden centers will sell you a lot of
stuff, like tree wrap, that isn't necessarily good for fruit trees.
Here is a link to Illinois Extension Service. Our extension service,
locally in Florida, is a great resource - can bring in weeds or pests
for identification and advice, talk to master gardeners for advice.
