Help a newbie out with products!

A little rant about me: I am a mama of two little boys and primping my hair is just not as fun as it used to be (and it never really was much fun). I completely stumbled upon the naturally curly girl "lifestyle" after researching the best brush to cut down my blow drying time and frizz. For some reason I came across the denman brush and this opened a whole pandora box of curly hair information. Now I feel likes I joined some sort of a cult and am obsessively watching women that have gorgeous hair but use like a million different products and dry their hair for something like 4 hours upside down (seriously?).
I went from 0 information to way way too much information and I really don't want to spend $$$ on hair products that will collect dust for five years then end up in the dump polluting our beautiful earth. So can somebody please please give me the coles notes version of what kind of products I should get and what to stay away from.
This is what type of hair I think I have (read everything with a question mark):
some mixture of 2B, 2C with some 3A thrown in on a good hair day. Very dry (mostly due to hair colouring) and fine texture, medium density on front, thick density in back, most likely low porosity.

Question: Are you following the CG Method? Co-washing only works if you aren't using products with silicons and waxes.
Product Recommendation: I think the Not Your Mother's Natural line is a good "starter" line for everything but the gel. There are 8 collections that have different set of ingredients. The conditioner's range from light to heavy (purple, dark blue, light blue, green, yellow, pink), so in my opinion, it's a good line to figure out how light/heavy you need for co-wash, leave in, and condition. I recommend start with the lightest and work your way up if you feel your hair can handle more moisture. They also have gentle shampoos if you decide co-washing isn't your jam. All products are $8.99 at Ulta and they frequently have buy 2 get 1 free sales on the brand.
Food for thought to add: Even if you aren't concerned with staying on the cheap, I think it's good to start on drug store brands as it helps you figure out what type of products work for your hair before you start doping bigger bucks. For example, you might figure out co-washing simply doesn't work for you or that you need mouse instead of a strong hold gel.

That said I have changed the gel I use and it has made an amazing difference. I am also experimenting with the techniques and attempting to pay more attention to what works and what does not.
These are just what worked for my mom and some of my personal thoughts in it too! She’s had naturally, what appeared to be 2A-b waves for years, never did anything with it until I nudged her to try to care for it for once and she had curls hidden under her wavy fine hair. She’s still trying to get the diffusing portion down (I don’t know it, probably never will) but she’s getting the hang of it. I’d put a picture if she wasn’t so camera shy.
Also, keep note, I’m a drastically different texture, as my mom has very similar hair to your own, except a medium porosity.
