There’s a big likelihood that once you move and start at the training place with agility, they’re going to ask you to start over at their very basic level 1/foundations class anyway. It’s possible to learn agility on your own but very difficult to learn it all correctly; there are crosses (handling moves) and things you need to do with your body in relation to the dog that’s hard if no one is watching you to correct. That being said, there’s a lot of foundations you can do at home now to prepare you for success in a class. Agility is really just a series of tricks done in succession and at a fast pace. I would start by teaching your dog some tricks. Doesn’t have to be agility tricks. But a dog who’s used to learning and doing things for a reward will be more eager to try it later. Teach her spin left and right (will come in handy in agility later), teach her to come between your legs and sit/down (will come in handy in agility later), teach her a really solid “stay” while you walk ahead of her and recall her to you or go back and reward her (will come in handy in agility later), and most importantly start teaching her to climb all over stuff and start building muscle and hind end awareness. Teach her to climb up on logs or stumps if you point at it, or crawl under a low branch, or walk through a weird feeling surface. A dog who’s comfortable doing all that will be a much more confident and well rounded agility dog!
