Daniel, my best advice is don't be afraid to experiment. That is the very best way to learn about your roses. Yes, there will be some disasters. In gardening of any kind that is to be expected. But every situation is different and if you don't try new things you will never know what works best for you. If you google ways to root cuttings or grow seeds you will find that EVERYONE has their own best method that works for them. They're all just a little bit different. Trial and error is the only way to find the one that works for you. And it's part of the fun of growing roses.
When I first started I had 16 roses in pots in Michigan that I needed to find a way to winter over. Everyone told me that the only way was in a garage and that was still iffy at best. I have NO garage! So I had to find a way to winter them outside. I created my own plan of storing them in a berm of burlap filled with leaves. People literally told me I was nuts. It would never work. I did it anyway and ALL 16 of those roses came back the next spring! Yes, like everyone else I do lose roses to the winter sometimes but that usually spurs me to try harder the next time. Try something new or different and see what happens. A lot of things I talk about I learned the hard way by trying them out on my roses and seeing the results. It is the best way I know how to learn. If I lose a rose I just think of it as an opportunity to buy another one! There's always something new out there I want, lol!
