Though not aftermarket, the Honda S2000 leather-wrapped wheel is a direct swap. It's the same size, shape, design as the Insight but is leather vs. plastic. I swapped mine a few months ago and I love it. I got mine used for about $50 from eBay. Because my car doesn't have cruise control and the S2000 wheel did, I swapped out the plastic housings so I ended up w/the S2000 rim + Insight airbag and housing sans cruise control buttons.

If you must have an aftermarket wheel, I'd guess the S2000 would be the place to start to see what fits that application.

The shift knob size/pitch is the very common M10 x 1.5, arguably the most common on the planet since its the same as other popular tuner cars like the Civic, Integra, etc.

I chose a leather Prelude knob for mine:
Honda Prelude KNOB, SHIFT *NH1* (LEA)(BLACK), 08U92-S30-100H, '97-01

(BTW - the boot is not leather, despite what the parts page above says)

For the boot, I did a custom Momo leather one that I cut to fit the plastic frame of the stock Insight boot. It came out nice I think.
