Check out my journal/tutorial, it’s a very long read but starts off with the info new growers are often looking for - seed starting and care of sprouts all the way to flowering and harvest. I don’t claim to have the best methods, just methods that have worked well for me over the years.
I’d hold off on a tent kit as they often come with inadequate lighting and cheaper components, a cheap exhaust fan will mean a noisy exhaust fan, inadequate light will lead to larfy buds and less yield.
We can help you put together a nice growing environment/tent with good parts.
What size tent are thinking about?
