Good bike specific rain gear.
Layers of clothing. A good motorcycle jacket is a must, than layer from there.
Chaps are convenient, they pop right off and store easily for non-bike activities in-route. They are great down to 45-50 degrees worn over jeans. I don't have specific riding pants with armor, etc. so they offer some protection on big-city beltway type roads.
I have a GPS now and find it indespensible. Without one a good tank tank with map top would be necessary (still probably handy)
Keep us posted!
