As far as quality, that shifter will probably break soon, and the freewheel might fail (it probably says DNP on it somewhere).
Neither is a particularly expensive replacement with better quality parts though.
SRAM 7 speed twist grip is $13
A real Shimano 7 speed freewheel is about $15 or so. I don't know what size, you'd have to count the teeth (i.e. does the big cog have 28 teeth or 30?)
Actually just changing those 2 things out would go a long way to helping the bike shift smoothly and for a longer time. You need a special tool to change the freewheel though - Park FR-1.
Your freewheel is broken, you need a new one like: https://www.amazon.com/Shimano-Tourney-7Spd-14-28T-Freewheel/dp/B003B8JYPU/
If you want to do the repair yourself you're going to also need a freewheel tool like: https://www.amazon.com/Park-Tool-Freewheel-Remover-Freewheels/dp/B001B6RGXG
And some grease when you thread the new one onto the wheel.
Here's a good guide on how to do that: https://www.parktool.com/blog/repair-help/freewheel-removal-and-installation
How is the chain slipping? Is is dropping down or hopping up a rear gear, or is it slipping forward across teeth of the same gear?
Just based on your language, and how I perceive your knowledge of how everything is working, you might be best served by visiting a bike shop. Please don't take that as a knock against you, but if you want to take it in, you will be well served.
That being said, where's the fun in that? Let's do this ourselves!
If the chain is slipping forward, it may be stretched. Check out Sheldon Brown's article on chains. You can measure the chain stretch using a ruler, since every full link (that's two half-links, the individual swiveling parts) is 1" pin-to-pin. Measure twelve inches and the whole 12" should be pin-to-pin on a brand new chain. If your chain is 1/16" past 12" measuring twelve full lengths, replace it. If it gets more gone, it will start wearing down the teeth of your rear gears, and you'll need a new cassette or freewheel, depending on your rear wheel. That will cause slipping and skipping for sure, even with a brand new chain!
If you replace the chain, you will need to get a cheap chain breaker. There are many kinds at different price points, but I can vouch for that one as I carry it with me.
For a new chain, you have to get one that is the right width. This generally depends on the number of rear "speeds" you have. Up to 8 speeds in the rear is a standard chain. 9, 10, and 11 speeds in the rear require a chain that is thinner to fit in between the close spacing between gears.
You can also get a master link and replace a link in your chain with it - you can then remove the chain and reinstall it (for cleaning and work) without using a breaker. That's just a random one I found on amazon, which happens to be for 10-speed chains.
Measure your chain, check your gears for wear. If you have to replace your chain you just need a chain breaker and new parts. If you have to replace the rear gears as well you need a new set of gears and the appropriate freewheel/cassette removal tool. There a few common types of freewheel tools and just one cassette removal tool. They lock in to splines and allow you to use a standard wrench or socket to remove the tool.

You linked to a freewheel remover. What you actually need is a cassette lockring tool.
As others have said get only what you need. However, unless you are going to frequently use the tools it may be cheaper to pay labor at the LBS for easy jobs than buying a tool you'll use once every year or two.
For flywheel you'll need
For the chainrings it's a whole new can of worms. It'll really depend on the crankset you have. Keep in mind though in most situations you can replace just the worn chainring and not the entire crankset. Cheaper and no special tools except an allen wrench. You wont even need to remove the crankarms from the bike.
That's great. I would bet any LBS would make the switch for you if you bought the kit there or you will need these
This
, probably this but different manufacturers have different ones
, And this guy
the tools are Super worth having but I here you're on a budget. Call up you LBS and see what they say.
As everyone already said, you need a new freewheel.
I cant tell if thats a 6 or 7 speed freewheel, but here is the 6 speed and
here is the 7 speed part you want.
and you need this to get it off.
There are a million freewheel replacement videos on youtube that you can watch to see how its done. Once you get the old one off ( and it will be a bitch to get off... most freewheels are) popping on the new one is stupid easy.

Here's a wheel. It has a quick release axle, but will work well.
You could either buy this tool to remove the freewheel (gears) and switch them to the new wheel or you could buy a new freewheel set.
hot damn theyre taking you for a ride. here is a replacement on niagra cycle. if youve got a freewheel removal tool you should be able to transfer everything over. only downside is that it might be slightly out of true when you get it.
