Welcome! The forum is a great place to learn about all aspects of the hobby, and to benefit from hearing about others' collecting interests. I would say just get on out there and get stuck in, collect whatever catches your eye at first, and see which way (or ways!) it ultimately goes.
I believe there are online lists of stamps covering certain topics, maybe someone else could chime in with the link?

If you're really stuck, a cheap worlwide kiloware lot will let you experience a lot of different stamps, and you'll begin to learn even more.
With albums, if you are unsure, may I suggest you start with stockbooks? These are relatively cheap, and are very flexible and useful. Even if you ultimately decide to invest in some bound albums, or to print your own pages, or whatever, you will always have a use for the stockbooks for keeping spares or organising stamps for mounting.
Have fun and keep visiting SCF!
