Okay, here is my adventure, so that no other newbie will make my mistakes!
First of all, I ended up getting the wrong gauge strings for my guitar. I honestly had no clue that there were so many different gauges. (Please, don't all laugh and point like I'm an idiot, because I feel kinda silly right about now.)
At first, I bought mediums, but when I called the store where I bought my guitar, they said that my guitar takes extra light strings (because it's a beginner's guitar pack). I should have gone there originally, but being a little further away, I opted for the closer store. Anyway, lesson learned (and I certainly got some practice changing guitar strings!!)
Now, onto yet another learning process: I'm not so crazy about the sound of these strings.
I mean, they're all in tune, but I don't know, I don't like the sound. I have D'Addario 80/20 Bronze extra lights, and I'd like to know what others enjoy. I'm pretty sure I'll be changing brands again, maybe several times before I'm happy, but I'd like to start off with some advice from you all out there.
Thanks!
PS: I have posted in another category another question about what songs I like to play, so that might help in deciding what type of strings I should have, if that plays any role.
