A couple of points:
Lighter strings may be easier to play, but there is a penalty in terms of reduced tone. "Thin strings make 'thin' sounds". You may also find that the reduced tension of lighter strings requires your guitar to be set up and adjusted to suit.
Acoustic guitar strings tend to be a size or two heavier than the equivalent for electric guitars. A medium/light set of acoustic strings is likely to have a .012" high E string. That would be considered very heavy stuff on an electric!
I use D'Addario strings on all of my guitars, electric and acoustic. I'm sure you'll be getting a lot of alternate suggestions from other members here. String choice is one of those intensly personal things that people get kinda touchy about! :D
