I would recommend inexpensive plastic LED pods for your navigation lights. They're very bright and draw hardly any current. I have two (one red, one green) mounted on either side of the V on my boat.
You can either screw them on or try an adhesive. Nobody likes to drill holes, but sometimes a mechanical fastener is best.
I also tried self adhesive LED strips, but the durability was not there. They start to peel where the heat shrink is applied to hold the wires on the end. They're good for interior lights, just not on the bow where they get bumped into the dock and pounded by waves.
As for the rear light, 36" high mounted white lights are pretty much standard.
