Tired of Leaks - Need help with my plumbing!!

I bought a house in November with a semi-buried AGP. I'm in FL, So there's no winterizing. I'm well aware it's not a super fancy, high dollar pool. And it's got some rust. But I'd love to make it last for the first summer at least, then I'll figure out what I'm doing, long term. I posted on Reddit, but didn't get much help.

The plumbing/equipment setup seems a bit janky. Every time I do something, whether it's emptying the pump basket, changing the filter cartridge etc, a leak seems to develop. There was a small leak at the filter outlet because the pipes aren't lined up perfectly. The filter is half hanging off the weird paver setup that the previous owner used. I tried to realign it, which made it worse. There was not shutoff valve, so I said, screw this, I'm installing a shut off. Well, in doing that, I developed a new leak at the pump outlet (feels like the threads on the pump are screwed up.).

I'd like to share my plans with the experts, and get some advice on what you would add, take away, or do differently.

Firstly, I plan to get one of those plastic equipment pads, and put all of the equipment on there. I was told to leave the "loop" after the filter. Though I'm not sure why, or what the 1-2-3-4 valve is for. Seems like a regular ball valve would work there? I'd also like to remove the shut off after the pump, and put one after the skimmer, before the pump. Does that make sense? Should I just leave it as is and try to make the leaks go away until next winter?

Should I bother with painting this filter? How are those cheap cartridge filters from Doheney's? Like these?

Thank you so much for any suggestions.

And here's some pictures of my mess.

Welcome to TFP.

You have the general idea. It is good all the piping is schedule 40 PVC. It just needs some TLC with new O-Rings, Pool Lube on O-rings, and proper alignment of unions.

I don't see any benefit to painting the filter.

What model and HP is your pump? You need a cartridge filter that can handle the pump flow. I am not sure that a filter rated at a max of 50 GPM is adequate.

You need to decide how much money and effort you want to put into the money pit when it will need to be replaced soon.

It's a 1hp Doheney's pump. I think it's a 6578? That might just be the motor P/N though. The only reason I wanted to paint the filter housing, is because I'm tired of getting fiberglass in my arms. I ordered a concrete equipment pad today. I would imagine I'll end up replacing it with a similar, but higher quality pool when it's time. I think the alignment of the unions is the biggest problem. I believe the threads are bad on the outlet of the pump. I checked today, and I can replace that part of the pump housing for only $20 so that's a plus. What about the 1-2-3-4 valve. Could that just be replaced with a shutoff if I have to redo that section of pipe?
 
I dunno the name either. I just noticed it has 1, 2, 3, and 4 marked on it. In the pictures, it's the valve between the filter, and the return.
That is a diverter valve.

Putting the handle in position 1 or 3 turn the flow off.

2 or 4 turn it ON.
