I have a relatively high volume (7,000) round barrel on my AR-15. When I need to replace the barrel, what else besides the barrel, bolt, and has tube needs to be replaced? How long do upper receivers last?

Impossible to say without knowing what barrel you have.
All barrels are not created equal.
Something like a CL CHF barrel from Daniel Defense or Geissele is going to far outlast something from Bear Creek Arsenal or some other trash manufacturer.
What is your firing schedule? Are you shooting groups or doing mag dumps?
A quality barrel that hasn’t been abused should last far more than 7000 rounds.
When the time comes for replacement, I would also replace everything in the BCG except the bolt carrier itself.
I would also replace the action spring if you haven’t replaced it before then.
I have never seen an upper receiver that has needed to be replaced due to wear.

1) I do not think of it as a number of rounds fired, I replace barrels when the groups start to open up. I usually look when this happens and it's because I shoot the throat out. I had to replace a DD MK18 barrel at around 12.5k rounds, I am over 20k on an SR15 and still going strong.
2) I usually replace the barrel, the muzzle device, the gas block, the gas tube. I have also had to replace the barrel nut.
3) I don't think of the BCG as part of the barrel. I do take my BCG out and clean it and inspect it probably more than anything else on the rifles. I will change pins, springs, gas rings, as needed. I do check headspace when I rebarrel.
4) I have never had to replace an upper receiver, unless I do something really dumb they seem to last forever.
