Thank you, Diptangshu. You've been a great help!

Ya. Just realized there are many websites with the wrong information... Here is another from a friend. http://www.skwirk.com/p-c_s-4_u-193_t-535_c-1998/VIC/8/Using-and-reducing-friction/Friction/Forces/Science/ "Reduce the contact between the surfaces. Have you ever tried to roll a cube...

This is the website: http://www.explainthatstuff.com/howwheelswork.html

It's becoming clearer to me now. But on this other website they mention "large contact area, high friction, box is hard to move". Does that mean the website is wrong?

How about wheels? Do we say they reduce friction or frictional force? Btw thank you so much for taking the time to guide me along. Much appreciated!

It's interesting that you say that friction is referring to the coefficient and not the force due to friction. Does that mean that friction and frictional force area different? Or is there another name we call the force due to friction?

I've read that the surface area of an object in contact with the ground doesn't not affect the frictional force acting on it as it is pushed forward. I kinda understand what is explained but I find it difficult to reconcile with what happens in real life... Don't wheels reduce the surface...
