chain wear/suck

I'm experiencing chain suck on my Klein mtn bike. The chain hangs
onto the chain ring and grinds up my chain stay when attempting to
shift from the middle ring to the large ring, or shifting from the
smallest ring to the middle ring. I examined the crankset and didn't
see anything that looked suspect, although I'm not sure exactly what
I'm looking for. I recently changed out the frame for a newer model
of the same frame. When I did that I replaced the chain, and shortly
thereafter replaced the rear cassette. I hadn't known about the need
to change the chain regularly, and had owned the bike for 8 years and
bought it used. As far as I know the chain was never changed in all
that time. My question is this, is it pretty much a 'for sure thing'
that my chain rings are worn and that I need to replace the crankset?
Is there a easy way to tell?

Thanks.

The short version is, yes you need new chainrings.

If you measured your chain and it was very worn, your chainrings are also
probably worn. No need to replace the crankset, you can buy individuatl
chainrings. Sometimes, it is cheaper to buy a crankset than individual
chainrings.
