Welcome to BB! Congrats on your new bunny. Are you planning to adopt from a shelter, or is the bunny from a breeder or friend?
As LoveChaCha mentioned, you won’t need the bedding. Some bunnies like having a soft place to lay, but filling the whole cage or pen with bedding is more harm than good. It makes a gigantic, smelly mess that’s nasty to clean up.
I’d strongly recommend getting wood stove pellets for litter. They’re absorbent, cheap (40 lbs for about $5) and odor-reducing. Just make sure that you don’t get any that are treated with chemicals.
Nature’s Miracle is great for cleaning up pee spots, but I’ve found that white vinegar works best for cleaning litterboxes. I also like sprinkling some baking soda on the litter and around my bunny room to get rid of the pee smell.
The willow hay rack is a cute idea, but if your rabbit is a chewer, it’ll be gone in a few days. The shelter I volunteer at uses stackable office crates for hay. They make great hay holders – they hold more hay than any other hay holder I’ve used.
Oxbow Essentials Bunny Basics T, if you can find it, is (in my opinion) the best timothy pellet for bunnies. It’s a bit expensive, but it’s worth it. I think Oxbow also makes an organic rabbit pellet, but I can’t remember the name. Another good brand is Kaytee Timothy Complete, although that brand does have some questionable additives.
For toys, bunnies actually like simple things best. Non-dyed cardboard boxes, dried apple sticks, phone books and cardboard toilet paper rolls are all favorites.
