I know this sounds really silly but put breastfeeding into Youtube search and many great videos come up. The advantage is you can actually see other mothers breastfeeding and this might give you tips on position and how to tell that you baby is getting enough milk to satiate himself.

Congratulations on your new addition to the family. Things really do settle down in a few weeks, especially when you gain confidence and can take your baby out in this wonderful sunshine for a nice stroll and can sit some where quiet and feed him. This helps the feeling you are doing nothing but feeding subside...
Good luck,
