The best guides I found for Confession with regards to how to make a good confession, why it’s necessary, etc were found on the multimedia page at Sensus Traditionis. They’re spiritual talks and homilies done by a priest from the FSSP who also taught at the seminary in Nebraska. I know you want something in writing, but honestly, they’re the best and most comprehensive guides you’re going to find (I’ve already scoured the internet when I had to make my “big” confession and was terrified of making a mistake and getting scolded for doing something wrong (as was the practice when I was a kid), especially coming from a traditional priest. He also has a couple good and thorough examinations of conscience posted on his site.
Going to Confession in the traditional form isn’t that difficult. Personally, I find it easier because there aren’t a lot of different responses you may have to make or may not, etc. It’s pretty streamlined.
As for saints talking about confession, I’m sure there are many. I make my confessions based on how St. Francis de Sales teaches in his book, “Introduction to the Devout Life” and what I’ve been learning from Heribert Jone’s book,
Moral Theology with regards to sins and the sacrament of penance.
The term “Reconciliation” is misleading, I find. I go to confession weekly, despite not committing any mortal sins, thus I do not need to be “Reconciled”. Only those who have broken their friendship with God (those who sin mortally) need to be reconciled.
I don’t know if this is any help to you, but it’s the actual form of absolution in the old form.
