That same jacket will work as a wind break layer in the winter, and you'll really appreciate it then.
If you're buying a bike, ask for something with mounts for fenders and a rack (fenders will do as much to keep you dry as rain gear will). You don't have to buy either right away, but I'd recommend fenders. Probably use a backpack for a while, assuming you have one. They're inexpensive (compared to bike specific stuff) and it will work. Eventually you might get yourself a nice bag and a rack.
You might also ask that the bike have enough clearance for wide knobby tires. You won't need them until winter, but if you do want to ride in the winter they're something you'll want.
Don't overthink it. Afterall, if you were really dedicated you could walk 2.5 miles to work
