Remember most first time parents are clueless. Human instinct is strong, just do your best. It'll be OK. You can never be truly ready.
Pre-made or easy but healthy meals are good - take a lot of the burden off. Newborns are tiring and time consuming but it does get better. Some kids are easier going than others. My daughter, other than a colic spell at 3 months, was amazing. We didn't now to her attempts at being fussy and she settled into a great routine.
I also read this after a close friend recommended it, IMO it's very good:
