In addition to the links that Pavlov gave you, try looking at this:

And once you have babies, this will be helpful:

Most importantly, READ a lot. I'd try to read at least one full year of posts in this breeding forum before you start pairing. If you just read all the new ones from now until fall, you won't actually see that much regarding pairings, seeing locks, etc. Obviously, you can go quite quickly through most of the posts that are just showing pics of stuff, so it really won't be nearly as much as it sounds like, and you have several months still.
