No need to balance any bias currents, just use 1K for R3 and keep everything else the same.

Thanks Peter!

Short follow-up question:
If I were to increase R1, would that require any bias balancing? I was simply looking at this from a standard op amp perspective, perhaps incorrectly.

No problem changing R1 value, I usually bypass that resistor completely.
