Starting out with acoustic is a rough ride for everyone. Strings play an integral part of playing, as that and the body of the guitar are the most important factors that go into your developing tone.
That said, anybody who's started out with guitar knows that when you first look at all those packets of strings at your local hole-in-the-wall music shop, your first words are probably going to be "I just need regular strings for an acoustic".
I've spent some time looking at different strings, but sometime at the beginning, I ended up with D'Addario Phosphor Bronze strings, and I cannot convey how happy I am with these strings. Once they're on, the sound is crisp and delicious, they make you want to keep playing, and eventually, start restringing every month rather than once a year. I'm not one for fresh strings on an electric, but Phosphor Bronze does the job well.
