That's about my commute. I've been doing it for a year now. My weight is finally under control (woohoo!). Obviously, I think it is a doable distance. That said....
Don't underestimate how much work it is. Prior to commuting I rode about 100-150 miles/week. Most of it was on the weekend, but I also rode 2-3 days during the week. It took me several months for me to adjust to the distance of the commute and be able to do the 5 days/week bike commute. Heck, I'd say that commuting 5 days/week is harder than riding a couple of days/week with a century on the weekend.
So, I'd recommend you start easy. Do a couple of days/week. When your body says that's easy, add another. Remember the idea of easy days where you ride at a pace that mimics a saunter, even if the wind is blowing hard.
Enjoy the commute. It is a great way to get your exercise. There is nothing better than a commute home to shake off the stress of work.
Oh, yeah...and for getting to know your city? I've lived here for 50-some years, but in the last year I've learned things about my city I never knew--you're right, commuting is a great way to get to know the neighborhoods you ride through.
