Good On you!
I've aslo only recently joined the EG world. Loads of fun.
Meticus Playing with a pick is not that difficult as expected. Easy tabs played slowly work fine already. Only when it comes to power chords I've still some problems catching only the two intended strings without touching a third.
In regards to the point mentioned. Don't torture yourself trying to only hit 2 strings.
Muting is where it is at. Modulator referred to it in his post above/below.
modulator You need to keep that skill, but using fingers "flat" is a skill you need to acquire sooner rather than later, and then, dampening strings not played.
