Why am I suddenly getting confused at this point?

My wife who arrived via a K-1 now has her green card, am I correct in believing our next step is to file another form a few months before the Green Card expires?

Yes - I-751 (and supporting documents), plus fees. Called Removing or Lifting of Conditions. Can be filed as early as 90-days before the PR/Green Card expires.

Step-by-Step Guide on Removing of Conditions (Form I-751)

ETA: Its a petition to kind of say (to USCIS); "Hey - we're still married, I can prove it, can I have a 10-year/non-conditional PR/Green Card now?"

You are absolutely correct and not confused - you'll file the Removal of conditions starting as early as 3 months before the expiration of her GC (just not prior to 3 months)

. . . and just as importantly you have to file before the 2 year green card expires so you basically have a 90 day window to apply.
