Personally, I find if i try to listen to podcasts or books while I work on something else my work suffers. Ill put something on to listen to if its really slow but if i actually have to "work" I cant have anything playing in the background. I tend to get into a groove when i work and having distractions keeps me from getting in that groove.
I used to have to focus my attention on at least two things. Like 80/20 or I couldn't focus. That 20% would be enough to keep my mind from wandering from the 80%
But, whatever works for you.
Personally, I think going without always on access to the web would do be wonders.
