Loving the thread so far, I'm in a similar boat too, starting the first ever build. Going the 1x route as well, I suggest that if it has enough tooth capacity keep it. I live in a hilly area and will build up my bike with an 11-32t, 8 speed sprocket paired with a 44t chainring, which would give me a slightly higher gear range to the current beater.
