@newt i personally started with the Donut series from Andrew Price (BlenderGuru) on Youtube. CGGeek also has a begginers tutorial series for a ice cream and Grant Abbit has one where you make a nice Sci-Fi scene with a robot gorilla, but it's also absolute begginer friendly.
After that, the Chair tutorial series of BlenderGuru is also good for learning more about basic modeling itself.
@newt nope nothing more than that. A grapics tablet it's mandatory if you wanna go into sculpting because otherwise would be imposible with the mouse alone, but that's absolute pro territory.
Do you use anything other than a mouse and a keyboard for input?
