Just thought I'd weigh in on the topic albeit a couple months late. Pick up "How To Brew" by John Palmer. It's a must, IMO, for someone considering getting into the hobby.
As far as dry yeast goes, I use US-05 exclusively for IPAs and the like when I want a nice clean flavor. If I'm making a hefe or stout or something where the yeast is supposed to have a good deal of emphasis on the beer's flavor profile, I'll use a liquid yeast. For cost and simplicity (no starter needed), I like using dry yeast.
The most important part of the brewing process IMO is fermentation temperature control so make sure you understand it and have something in mind.
