Hi welcome aboard.

I am a recent starter too, but from what I can see you have a good bit of kit there. Wackers are great razors, and the modern Dovos too. The strop you have is fairly typical and will suffice for now, you should definitely not paste it. The yellow paste in a tube is the most you should use, this is fat to condition the leather, but olive oil or mink oil is also used - though this is not essential. The soap and brush are also good quality. You can buy brush stands for very little that will hold it upside down.

You should get those razors honed before you do anything else - my first recommendation would be to send them away to a honemeister. You do not state where you are in the world, but if you let us know a honemeister local to you will chime in for sure.

As to a stone - eventually you will need something to refresh the edges, and you may even decide to start honing yourself. Most people seem to. The generic recommendation is for Norton 4000/8000 stones, and most of the instructions on the site are geared towards that particular stone. There are many other stone choices though, and it is all about personal taste. Again depending on where you are in the world, stone choice may have a lot to do with it as Nortons are only available in the USA.

I personally shave using only my right hand, many others are ambidexterous shavers. I think if you can use your left hand, its a good idea to start building up those motor skills, but when I tried it I really felt like I was going to slice the side of my face off.

The biggest thing you will need is patience - this is not an "instant gratification" hobby. It took me about 10 shaves before I was even comfortable holding the razor to my face and was relaxed enough to enjoy it. It took at least another 20 before I was able to look at my face and be really happy with what I had achieved. I developed fast too - there are guys here who have been going months and still aren't getting the shave they want. I think even the guys who have been shaving years will tell you that they still learn things.

Hope you are still awake - I tend to ramble in posts. Welcome aboard, and enjoy the journey!
