Welcome back! I too had a 20 year break, unfortunatley I sold my roadbike before returning, big mistake!!!! Hang on to your Fuji. start slow and build up, in no time you'll be putting big miles under the saddle. In a year or so, you'll have a better appreciation of what you have and what you want to improve. I'd just do a tune-up and a nice set of tires to get started.
