For what it is worth, and I am not a professional groomer (not even close), I use the below products. Why? Because the person I have taken classes from uses this stuff and recommended it. And, they all smell really good.
For a dryer I use the little orange Metro. No heat. I've had it close to 20 years and it keeps on ticking. Wish it would die so I could buy a better one. Most of the breeder/handlers I know use and like some version of the K9 III dryers but those are really pricey for people like me that don't show, but just try to keep their dogs looking decent and clean.
What I don't like about the little Metro dryer: It's really noisy. The hose is too short. It's really noisy. With the expensive pro dryers, they are more powerful and I've noticed the hose is much longer which allows the dryer to be placed a little further away reducing the noise.
I'm horrible with trimming nails. I don't do it often enough. I was shown how to use a Dremel and sometimes use that.
Shampoo - I pour some of this into a small bucket, sometimes add a drop of Dawn (don't ask, I don't remember why...), and wash the dog down with a washrag in a dedicated doggy bathtub... Follow the directions on the bottle if you use it.
Bodifier. Mixed into a spray bottle. Nice stuff. Smells great. Use it mostly in the fluffy areas. Follow the directions on the bottle if you use it.
Mixed in a spray bottle. I use it like a conditioner. Follow the directions on the bottle if you use it.
Rarely ever use this. Not sure why I have it... Follow the directions on the bottle if you use it.
