Reddit mentions of Living World Nature's Perch, Small

There is nothing morally wrong with getting parrots from a bird rehab center. They don't breed for profit, just rescue and care for birds. By adopting from them, you are supporting them and making more room for other birds. So, as long as you can adequately take care of the birds, it's not a bad thing to do.

My understanding is that lovebirds are pretty similar to parakeets (which I have), so I could probably give you some information. There's no need to file their talons or beaks, as long as you have the appropriate stuff in the cage. Typically, the kinds of perches that come with most cages are rubbish. Birds need perches with varying widths and textures. Stuff like this or this is awesome. These textures and width variations keep the talons worn down properly, so that they do not need to be clipped. It also is good for their muscles, I believe. Give them lots of things to chew on, and that should keep their beaks in line. This way, you won't have to touch the bird to clip their wings, talons, or beaks, which could really scare the bird if it isn't used to you.

Feeding them the food in those bird food bags at the petstore isn't a good idea in the long run. It's not good for their health. Try feeding them fresh vegetables and fruit if you can, as well as the generic bird food. It's likely they won't like the fresh stuff at first, but give it to them fairly consistently and they may give it a try.

A cage is absolutely necessary, simply because you need to have a place to put them where you know they'll be safe. Like if you're cooking or have all the doors open for moving furniture in or out. The birds should not be loose in the house during those events. I'm not saying you should lock them in their cage all day, just at certain times when it's necessary. Also, keeping them there at night gives them a sense of security in that space. Ideally, you would have a room in the house that you know is bird-proof, where you would feel comfortable leaving them out unsupervised, but you should still have a cage in that room, as a safe haven for them, where they know they will always have food and water. When out flying, they typically like to have a few favorite places to perch. One of these should be the top of the cage.

The cage should be large. One thing to remember, though, is that "tall cages are kind of useless. Birds will typically move to the topmost part of the cage and stay at that height. Instinctively, they prefer to be at the highest available location. So, a cage like this is, in all practical use, much smaller than it looks. A wider cage is better than a taller cage, as far as giving them space. A wider cage might mean that they could fly a short distance from one perch to another. A tall cage is basically a small cage. Also, you want the cage to have horizontal bars if possible, on at least two of the sides. Parrots are big on climbing, and horizontal bars, as opposed to vertical bars, are great for that.

I'm procrastinating right now so can't go into much more detail right now, but if you have any questions, just reply :)

Your bird will be fine without sleeping in your room. My cockatoo has her own bedroom where she sleeps every night. The room isn’t used for anything but that.

As far as birdy stations, I have one in my living room and one in my bathroom. She also has a small perch in my bedroom just for when I’m doing small chores in there and she wants to be with me.

You need to replace the perches that you have in that cage though. Perfectly round perches aren’t great for your bird’s feet. I’d go for perches like this instead. I’d also add more toys so when he/she is in the cage, they have plenty to occupy their mind. They need so much stimulation.
