I think it's great that you're starting to study the piano with a background that allows you to read music! That's the thing that stops so many people in their tracks: they have such a hard time getting from the paper to the keyboard!
Everybody here may give you different opinions/advice, but mine is to learn to play what music you like that's not at such a high level, you'll get discouraged. What I'm saying is two things, really. First, keep yourself motivated by actually liking the music you're learning. And, second, don't be intimidated by pieces that are beyond your current technique (as long as they're not ridiculously hard!) that you want to learn to play.
I make my fastest progress when I challenge myself with pieces I'd love to play that are a bit beyond my skill level. But also, it's important to have some relatively easy pieces that you like hearing yourself play. I recommend you look at Burgmuller's 25 Easy and Progressive Studies, which is his Op. 100. Many of them are so musical, you hardly feel like you're practicing for technique, unlike LOTS of books for beginners.
You can find these pieces as well as SO many more by clicking on "piano music", above. If you're paying member, you can download as much as you want. And I think they still have a trial membership with some downloading privileges.
You didn't mention if you had a teacher, but if you can find one you relate to and like, that will help your progress immensely, too!
Good Luck!
