As to the second: daily, more or less.

Personally I prefer a good dark roast, and if it's a good blend (also for medium or light roast) I want it black.

Outside of dedicated coffeehouses though, most coffee out & about isn't what I consider "good" (I guess I'm a snob?:-P), so I usually add sugar & creamer.

(Pro-Tip: combine black coffee with a pastry for the ultimate snack, i.e. the sugar doesn't need to be poured directly into the liquid! The juxtaposition of the bitter and sweet really works well.:-)

I can't stand Starbucks coffee regardless though, so if needed I'll get a mocha. I'd sooner trust a McDonald's coffee though - seriously: b/c Lavazza is great!

It's such a personal choice though - what do you like?
