Need advice on my odd setup

(Was told yall would love my setup so im crossposting, thanks!)

I was given a sounddesign 958p record player and receiver combo along with some sony mb300h speakers. My ideal setup is basically speakers that connect to a decent record player that double as my tv speakers, in a perfect world that can also connect to my phone. My budget is somewhat flexible, but I really really don't want to spend more than 500 total, including even a new tv? I know this is not a speaker or TV sub so I guess my question is do i stick with this record player? I have seen people say that the best way to replace the needle on one of these is too burn it in the backyard, and I don't want to fuck up my records because they are pretty expensive. Something just sounds off right now and I'm really struggling to find a replacement needle. Thanks!
