What do I need for range day

Ok I know I am asking a loy of newb questions but when it comes to nee hobbies and especially where I will be doing them in public, I like to have confidence that I don’t look like an absolute clusterfuck.

So in preparation of going to the range what can I do to make life easier on myself. Meaning how should I transport my handgun and ammunition and eye and hearing protection. What do I need to not only look like I have my shit together but also to be in compliance with the law and most range rules? If it helps I am in MN.

I was looking at some range bags but they don’t seem to lock and wonder if that is something I should be looking for.

What do you do? What is your setup?
