2007, ac works only at above 2.5k rpm. Want it working at idle, what to do?

ugh, my AC stopped working last week, on the way back from a trip to Canada.
Everything was great and 'cool', until I was a few hundred miles away from home on the highway. I noticed it started to get warmer in the interior. I thought maybe it was getting warmer as it was sunny, around 1PM with the sun moving around its highest point in the sky. So I lowered the temperature, eventually all the way to "LO" with warm air starting to come out the vents.
205k miles
Got home and put some AC manifold gauges on the AC lines, and they show around 140psi low and high pressure sides with the compressor off obviously. So there is refrigerant and no leak. Fans turn on when I press the 'Auto' button+'Lo' temperature setting. Swapped the top "snowflake" relay on the box with another one, no go. Read the A/C clutch circuit procedure on the FSM and put a jumper wire on the pin slot 1 and pin slot 2 on the "snowflake" relay. No compressor movement.
So I am assuming and hoping the clutch mechanism parts is no good anymore. I never heard any sound prior to noticing the AC no longer working, and I can easily spin the front of the compressor with out feeling anything rough.
Planning on getting the refrigerant sucked out, replacing compressor and condenser. The fins on my condenser are pretty beat up from road debris, and the reciever/dryer should be replaced when opening the system. Might have to add more parts if the compressor oil has debris or any other evidence shows up.

I bought a $155 UAC compressor that was mentioned on this thread. No way I was paying for the original part. I plan on installing it in a few days. Also found this screen filter on Rockauto https://www.rockauto.com/en/catalog...air+conditioning,a/c+refrigerant+filter,15479 that is supposed to go over the suction line entrance on the compressor (I think?). It is supposed to protect it from debris. It has very little information and is not in stock there, so I ordered it from CarID.com (the only other 'known' place I could find it at). It looks almost identical to another product I was looking at first, on the Autozone website, "AirSept Compressor Guard" but it only ships from Autozone with more than one week estimated delivery. Hope it fits easily and works well.
Those prices are hhmmm, high
. Are they doing anything else? I'm starting to get annoyed at AC problems and work. I wish a proper fix just involved replacing a compressor or part + topping off with refrigerant:| Goodluck to all driving in this summer weather.
I have the compressor, condenser+reciever, and radiator installed on the car again. All new.
When I drained the oil from my old compressor to measure the quantity inside (turned out to be 1 oz), it came out looking clean, but with a small amount of sediment and debris. So now I am ordering a new expansion valve and evaporator. Not looking forward to being stuck under the dash
I don't know what to do about the hoses, I want to get the car ready and I fear I am wasting the desiccant element inside the receiver by opening the system every time I am removing an AC component.
