Smithing is easy. I used whiterun as I'd bought a house there. Buy iron and leather from the blacksmith. Forge loads of iron daggers. You'll run out of iron quicker than leather, so then make loads of leather bracers. Sell them back to the blacksmith. Go to sleep for 48 hours in your own bed, then go back and buy some more iron and leather. In the space of an hour, I'd maxed out Smithing and made Daedric armour, which IMO is cooler than the dragon ones. I also had a smithing thing which helped me make legendary armour.
