Yes very normal..buy thr lanisoh nursing pads I like thoses bc they stick better to your bra
Get some reusable nursing pads too. They are nice to stick in your bra so if your leaking its not getting on your bra / shirt. They are only like 3.99 that is what i am sticking in my bra.
Completely normal. About the bras, if you plan to breastfeed you can go ahead and buy nursing bras now to save a bit of money. That way, you won't need to buy bigger pregnancy bras and then nursing bras. You can get whatever is comfortable for you, they just say to avoid underwire when nursing.
