Cattleya crawling out of its pot

[HentaTenta]

Hi. A friend had this cattleya and was ready to throw it out. I decided to attempt to save it, just never saw a plant getting out of pot like that.
Should I get rid of the majority of dead stems?
Do I orient parts that are alive towards the middle of the new pot?
There are some roots that became aerial, do I force them inside potting media?
Please advise
Thank you
