I was recently exposed to the topic of Information Geometry by a friend of mine, and was looking for a good book to begin self-studying this topic. Any suggestions?
Also, what subject matter would one need to have a handle on to begin self-studying this? I have an undergraduate-level background in real analysis, some basic point-set topology, as well as algebra up to the level of Galois Theory.

The most famous book on the subject is probably:
But there are few other ones that look quite nice:
The last one mentioned is quite new.
This question has been asked quite a few times in different ways on the SE network. Let me link to a few here:
For the background/prerequisites, I would say they are:
Differential geometry: manifold theory (differential forms, connections, etc) and Riemannian geometry (metric and curvature tensors, geodesics, etc)
Probability and statistics: probability distributions, statistical estimation, basic measure theory, and information theory
