So I have this really old classical guitar and I the current set of strings on there are most definitely stretched out, and it plays out of tune passed around the eighth fret.Not really sure what to do with it

Classical guitars tend to have greater string relief at the upper frets because the strings vibrate in a wider arc. So, it's always a problem that at the upper frets you tend to "pull the strings sharp" due to the distance to the fret.
Likely with your older guitar this may have become worse due to the bridge area rising or whatever... Even humidity problems.
It's unusual for the intonation itself to be off much... The frets and bridge don't really move.
Have the action checked. It may be that a new set of strings and a bit of saddle relief will put it right.
