Help finding Wy/CO/NE shop for EGR + other 200k mile tasks

My 2014 V turned 200k miles recently, and so I was looking at the forum trying to figure out which maintenance things I should do. I got the car with 60k miles, and I've done mostly all highway miles on it to get it over the 200k mile mark. For those who helped last summer, I got the famous death rattle and early HG warning. I found a wrecked 2015 with 55K miles and a local shop put that engine in (10,000 miles ago now). I've done oil changes and new brake pads, and a new 12v battery a few years back. The ATF has never been changed, as best I can tell. And I don't know if the new/used engine came with the EGR or exhaust manifold, but something in my mind says I should get those cleaned. Also, I'm guessing the water pump is still my old one (doubt that came with the engine swap last summer-but not sure what the signs would be that I need to replace it).

I've looked at the videos for the EGR cleaning and manifold steps, and it looks pretty hard. I do my own oil changes, and brake pads, and I'm medium hard-handy, but don't have a shop--just my scissor jack in the driveway.

I live in WY, and am looking for 1) tips on what I should be doing for my 200k mile birthday spa for the V, and 2) if there's a shop within 300 miles of Laramie, WY that is good with the V, and could do the EGR, transmission fluid, etc, that you all trust. I am leaving to drive to NY again for the summer, and want to do a few things before I drive 2000 miles alone in one go!

The car still gets 42mpg each tank, burns no oil (still looks perfectly clean btwn oil changes) and since I'm in WY, there's no rust (we don't salt roads).

Any tips, suggestions, thoughts?

p.s. i could do the transmission drain and refill, but the car needs to be up and level, and I don't have the jacks and ramps to do that in my driveway. the Toyota ATF is $80, and the Toyota dealer (conveniently walking distance to my house) charges $200 to do it, so I might let them do it.
