You'll find that most often players will make their highest stats prime anyway. And they will amost never make their lowest stats prime. So it's not very difficult to come up with a background for those attributes and the primes.
A prime is generally thought of as your level of natural talent while each attribute is the level to which you have devloped yourself in that area over the years. So the Str 10 prime is the character who has never bothered to work out or develope his muscles. In fact, he probably hasn't even done much in the way of hard labor in his life. But, ever since he was a young boy, people always talked about his great strength. Even at a young age he was easily able to perform feats of strength that his older brother found very difficult.
Now your character with the 18 str that isn't prime is one who has little natural inclination towards physical strength but has (maybe in an attempt to compensate for that) always worked out and done his best to augment his muscles. So he's quite strong but he just doesn't have the type of body which takes to feats of strength.
I think most of us will agree that natural talent is often better than those who just work hard at a skill. Now, of course, the best of the best are those who have both.

So C&C requires you to look at stats slightly different than in the past but it's not a big leap and it's a good one in my eyes.
As for the bard, this is a character class that C&C has almost reinvented. It still tries to depict the same sort of learned storyteller but it gives you more freedom in how you see this character.
Exalt allows the bard to give allies a +2 bonus to most any non-attack roll for a short period of time. How the bard does this is up to the character but some examples are song, battle cries, oration, etc.
Fascinate allows the bard to entrance a single creature and, as the bard increases in levels so too does the power. So the bard is able to hold a single creature's attention at first and, later, is even able to suggest certain actions to that creature (or person).
Exhort Greatness is a bit like exalt but it is more combat oriented and has more bonuses. I'd equate it to raising a battle lust (though it doesn't drive one into an unthinking frenzy or anything).
So, as you can see, the bard has some of the same functions as he always has but quite a few more applications a well. And with the Legend Lore ability which is "a little knowledge about a little of everything" the bard is a great addition to any party.
But you'll also find that the bard has d10 hit points, an attack progression equal to some warriors, and a decent choice of weapons and armor. So this makes him quite the capable secondary warrior as well. If you think of the bard as the scalds of the norsemen then you're right on track (at least that's how I think of the default C&C bard).
