Glory to Jesus Christ.
I came out of the PCA myself, and it took me quite a bit of wrestling with myself before I would commit myself, then several more months of trying to convince my then-girlfriend. When we finally split (it was a long time coming, even before I discovered Orthodoxy), I enrolled in the catechumenate.
I don't know really anything about the particulars of your remaining issues, but mine were mostly theological, and I spent A LOT of time in books (about history, theology, etc.) and in front of my whiteboard trying to figure it all out. That definitely did help me, but something that finally made it click in my heart was reading the wisdom of the Fathers (particularly the Saying of the Desert Fathers) regularly attending the daily services and establishing a small, steady prayer rule for the mornings and evenings. It did wonders for my soul and aligned my heart with Orthodoxy.
My stubborn head took a little while longer, but because I struggled to live alongside the Church, I eventually stopped examining Presbyterianism vs. Orthodoxy on equal footing, and started studying on how to disprove my own Protestantism and align my mind with my heart (which had already fallen in love with the Church). If it doesn't sound scholastic...it's because it isn't. It didn't make sense then, and it doesn't now...but it brought to the point of desiring communion with the Orthodox Church. It honestly felt like scales were (metaphorically) falling from my eyes.
My prayers are with you and your wife. Lord, have mercy.
