Trying to be a better chinchilla owner?/

Hi!
I am new to this site and this is my first time posting so I'm sorry if I put this in the wrong thread but I need advice on caring for my chinchilla.

I am 16 so I live at home with my parents, the chinchilla is mine though, so everything I want to do has to get passed them. That is the first problem because a little while ago I had a concussion which worried my parents on how I slept, anyways long story short my chinchilla can no longer stay with me in my room overnight. The problem was that he was in my room all the time and now my mom makes me move him before I go to bed in a totally different cage downstairs so I can get good sleep. I feel like this is bad for him though because I constantly have to move him which I feel like must cause him a lot of stress? We keep him in my room during the day though because we want him to be around people as much as possible throughout the day so he doesn't get lonely. Is there a better way to do this? I can't leave him in the common rooms so I have been leaving him in a "storage room" at night. It is a good temperature and carpeted and stuff like that, it just doesn't get a lot of attention.

Secondly, I used to let my chinchilla out in my room to play because it was the most convenient at the time. After him chewing on my wood bed and me being worried that he would get to something that could possibly hurt him, I decided to take him to the bathroom or playroom to play. I always have issues getting him there though, since he doesn't have a cage there and I have to pick him up. Sometimes he doesn't mind me picking him up, I think he bonded to me, but other times he doesn't really like being picked up too much and I don't want to stress him out too much. Is there a better way to do this because I hate deciding whether to make him angry or skip play time so I keep him less stressed but then he doesn't get to play? I use the dust bath to get him in after he is done playing but I don't think using it twice is good but I'm not really going on anything so I am not too sure?

Third (I know this is long, yikes) I want to get my chinchilla a critter nation so he can have a proper cage. The whole two cage thing is really throwing me off so I have a smaller one in my room during the day and a big one downstairs at night because I assumed that he would want to play more and have more room downstairs. I am guessing the ultimate goal for me would be to somehow come up with a way to get him in one cage all day and all night in one location and then invest in a critter nation cage. If the two cage thing is okay and you guys think it wouldn't stress him out too much, is there any cages you would recommend because the ones I have now aren't good and I know that but they were kind of temporary cages that ended up lasting way too long.

Also, am I supposed to take my chinchilla to the vet once a year like a dog? I just thought of it the other day and now I am freaking out because I never took him and I'm scared that he might be sick and I just never knew. He hasn't shown any symptoms I think I am just being paranoid but is it something that I should do anyway?

Those are my four main questions but if you have any advice based on this or any random advise you think may apply please let me know. I am so stressed about this but I am so cluless and it's hard because unless i know for sure it's hard to fight my parents on it if that makes any sense.
Thanks so much if you made it through all of this I know it has been long!
