I'd also love to read some ride time/break time summaries for others that completed their 1st century.
If you can ride 50-60 in 3-4 hrs, you'll be fine and definitely are fit enough to do this. You should take an easier pace than you would for these shorter rides, and I strongly recommend not looking at your speed when riding. Don't calculate your speed either -- consider not even keeping track of the time.
Allow all day. You won't need it, but don't push yourself against any artificial time barrier. If you do, you could be in a lot of pain near the end. Be sure to eat and drink plenty. Take breaks when you need them, and expect to want more towards the end. Probably every 25 miles or so is good idea, but don't be afraid to take more if you feel like it.
