Since its your first bike, I'd say go with a good helmet, some good gloves, a mesh jacket and some leather shoes or boots. Sounds like its an easy and quick commute so I wouldn't think you need to go over the top. Personally I rock my Scorpian Exo 700 helmet, Alpine gloves with carbon fiber knucks, good thick jeans, a pair of leather Puma tennis shoes and my Cortech jacket. It doesn't sound like you'll be knee dragging curves at 80 so you shouldn't have to worry about knee pads or leather riding pants. Top speed through town would be about 45, if that, yeah you'd be fine with what I've said. Quality products does go a long way though. I can only impose my opinion, which is, safety has no price limit. If it's a better product by all means pay extra for it. Lots of happy safe miles my friend.
