I just ordered a WO Zenithstar II 80 with a WO binoviewer. Anyone here can recommend which eyepieces I should use for this combi?

Your WO binoviewer comes with two WO 20mm WA eyepieces as part of the binoviewer package, right?

If not, depending on your budget, you can consider a pair of 24-26mm plossl (52 deg AFOV) or a pair of 18-21mm wide field (65-70 deg AFOV) eyepieces to start with.

Yup. It comes with 20mm eyepeices. I'm thinking of using it for views on the planets. Any suggestions?

For my ZSFD 80mm f/6.9, I use a 3.5mm eyepiece to get a good monocular 'high' view at 158x. I wouldn't get an EP pair just for planetary views due to the limiting aperture and limiting use for a 3.5mm pair, as I have bigger scope would serve that purpose better.

I have not used the WO ZS II, but if it is not an apo, it is usually not recommended to push beyond 100x magnification. But it should serve well for giving low-power wide-field views.

It's an apo..

But it's using FTL-51 glass and not the 53 used by the ED 80. I'm thinking of using a 10mm pair and a balow to push it up for planetary viewing. Not sure if it's suitable.
