Miyata makes terrific bikes and this is a good one in terrific shape. The tape is benotto tape which is so-so. It did come in colors. It will be easy to remove and replace with some decent handlebar tape. There are reproduction hoods you can buy that should work pretty well. I like Cane Creek hoods and they come in black and gum. There are lots of great choice on tires but the go to tire if you want a gumwall is a panaracer tire. They're good tires and reasonably light.

By the way, a bike that old needs more than just a cleaning. You should take it apart so you can overhaul the hubs, bottom bracket, headset, and pedals. You will want to replace the consumables (chain and cables and cable housing). You will likely want to change out the brake shoes as they tend to get hard over age; replacement brake pads are available.
