If you're going to be riding at night I suggest you get a roll of reflective tape and put pieces all over the place...wrap every member of the frame, the crank arms, handlebars, etc. etc. There is no such thing as too much visibility for a bike.

Those baskets are going to be heavy. They'll help get the groceries but you'll notice the difference when you're not using them but still dragging them around. I used a plain rack that I would zip tie a milk crate on to when I needed to deliver stuff, then take it off for rides where I didn't need them.

Seatpost with shocks. Comfortable saddle. Front/rear fenders, the light plastic ones are fine. Rain gear.

Glad to hear someone opting for a bicycle!
