Problem 1,
https://philcoradio.com/phorum/showthread.php?tid=16833  Read post 6 there are two screws that adjust the arrow mask position. I'm making a couple of assumptions that you have the chassis out of the cabinet, that you either have removed the 80 tube or have the spkr plugged in, the dial is centered properly onto the flange, and that all of the dial assembly is put together properly.

Hello Terry to answer your first question or comment, I've tried adjusting the position of the arrow mask several times and I can't get it to center correctly, it's either too high or too low, I can't seem to get the pointer arrows to center exactly in the center of the mask.

Problem 2,
Not sure. Have done a half dozen or so of them and have never had one that was hard to turn afterwards. Would think that it's not assembled correctly or something on the outside is causing it to bind. I have had the outer knob feel rough when turning it. Have read that it can be caused by the ball bearings having flat spots on them from wear. This last one I did I lost one of the balls and got a sack of replacements of all different sizes. Found the right ones and replaced all three. After I got it back together it was still rough. Am thinking that it's from the shaft being worn.

The issue you said you had with yours, is the issue I'm having with mine, the outer knob (which is the coarse tuning knob) is what's turning hard and rough compared to the inner (fine tuning) shaft which turns smoothly. 
Fortunately I still have all three of my original ball bearings yet, and from what I could feel on my ball bearings they didn't feel like they had wear spots on them. 
The weird thing about the problem I'm having with my tuning knob is that the rough turning of the knob seems to go away once I push in on the inner knob shaft and then turn the outer knob shaft, once I do that the outer knob shaft turns smoothly as it should, but as soon as I let off the inner knob shaft the outer knob shaft goes back to turning roughly again.
The other thing is that the outer tuning knob was working fine before I disassembled it, then once I disassembled it to clean and lube the tuning knob assembly and then reassembled it, that's when the problem started happening. 

Problem 3,
Not sure which clip you mean. There's three to choose from. Small one at the far end of the planetary drive that's the one you have to pry open to get off. Large one that clips into the planetary drive kind of a piece of springy wire that clips into a slot. And finally the flat spring clip that fits into the knob to hold it onto the shaft it's press onto.The 

The clip I'm referring to is the small D-shaped spring clip that goes in the slot on the top of the tuning knob assembly housing to hold the tuning assembly together. 
When I first went to disassemble the tuning knob assembly the clip wasn't present, but then I had found it sitting on top of the radio chassis behind where the tuning knob assembly would of sat, so then when I disassembled, cleaned and relubed the tuning knob assembly and put it back together again I reinstalled the clip, but then I was noticing the aforementioned problem with the tuning knob assembly where it was tuning rougly, so I removed the tuning knob assembly from the radio again and disassembled the tuning knob again to make sure everything was assembled correctly and it was and so when I went to reassemble the tuning knob assembly again I got everything put back together and that's when I noticed that the D-shaped spring clip was missing.

I hope that helps you understand better what I was trying to say in my post about my problems I'm having with my tuner.

Also my staff person that works with me from a local organization that works with people with disabilities, seems to think that me gutting those bakelite block capacitors is going to be somehow harmful to my health just because he had read an article online somewhere that said that Bakelite supposedly was toxic and that was why they discontinued it.
I would like to straighten him out once in for all concerning that matter, and if it helps any he's one of those people that buys into that extremist enviriomentalism of the extreme far left, so it wouldn't surprise me if that wasn't where he got his "information" about
the supposed toxicity bakelite, I told him that Bakelite isn't any more toxic than any of your modern plastics and the only way you would release any potential toxins that would be in it would be to actually melt the bakelite which just heating up the bakelite with a heat gun set on low isn't going to be hot enough to melt the bakelite, because Bakelite has a much higher melting point than modern plastic does, but he didn't believe me, he was more willing to accept what an article online sourced from who knows where that he never even bothered to fact check said.
