It’s recommended to trim hooves every 6-8 weeks. If you only have a few you can do them all on the same day every few weeks. I have so many goats now that it kills my back to do them all at once, so I check them every few weeks and trim one goat a day
You can shave udders whenever you want, a lot of people do it before kidding, but you can wait until you start milking, or not shave them at all, depending on what you want to do
I just wanted to add a few more tips if you’re interested

Best Goat Book Ever
Records: I recommend keeping records for individual goats. I keep a 3-ring binder with a separate file for each goat where I put their registration papers, medical history, breeding records, and sale history.
In some states such as my own you are required to keep these records (mostly medical) for several years. The main purpose of this is for meat and milk withdrawal times and to trace disease
Registration: If you’re planning on breeding to sell, you’ll definitely want to get good quality registered stock, and you’ll get out of having to use scrapie tags as long as they’re registered and tattooed
Testing: You’ll want to start out with goats tested negative for CAE, Johnes, and CL. These are serious diseases that can go by undetected or take out your entire herd. Most serious breeders will test. I got lucky with mine, but it’s so much easier to start with tested stock than to replace infected goats that you love
That’s all I can think of right now, but feel free to ask any questions you might have
