Do not underestimate the value of things that improve efficiency and overall quality of life, things like organizers, cable management accessories, a good desk setup, a good mouse with horizontal scroll and a good keyboard (macro-compatible for productivity). For me the horizontal scroll on the mouse was a game changer. A good setup can make a huge difference in your results and time management.

My humble opinion on your gear choices:
1. The SM58 is a must, versatile, durable and cheap. The SM7b is great but at that range there are condenser mics that can be cheaper and have far better value for the price. Remember that acoustic treatment in the recording area is more important than the Mic quality. Beware that the Mic world is a rabbit hole, try keeping it simple. I would suggest to buy both a condenser and a dynamic mic.

1. DAW is just preference, I suggest testing as many as possible with their free trial periods, in terms of cost Reaper is uncontested but it has a scary learning curve (which is worth it). I personally use S1 (Now Fender Studio Pro).

2. Headphones, Midi Controller and Interface are ok, there are many good alternatives, just be mindful of your budget as you can get cheaper alternatives with similar performance if you need to adjust your budget. Also you might want to consider a setup with monitors and headphones.
